    • Target

    • Function
      Integrins alpha-1/beta-1, alpha-2/beta-1, alpha-10/beta-1 and alpha-11/beta-1 are receptors for collagen. Integrins alpha-1/beta-1 and alpha-2/beta-2 recognize the proline-hydroxylated sequence G-F-P-G-E-R in collagen. Integrins alpha-2/beta-1, alpha-3/beta-1, alpha-4/beta-1, alpha-5/beta-1, alpha-8/beta-1, alpha-10/beta-1, alpha-11/beta-1 and alpha-V/beta-1 are receptors for fibronectin. Alpha-4/beta-1 recognizes one or more domains within the alternatively spliced CS-1 and CS-5 regions of fibronectin. Integrin alpha-5/beta-1 is a receptor for fibrinogen. Integrin alpha-1/beta-1, alpha-2/beta-1, alpha-6/beta-1 and alpha-7/beta-1 are receptors for lamimin. Integrin alpha-4/beta-1 is a receptor for VCAM1. It recognizes the sequence Q-I-D-S in VCAM1. Integrin alpha-9/beta-1 is a receptor for VCAM1, cytotactin and osteopontin. It recognizes the sequence A-E-I-D-G-I-E-L in cytotactin. Integrin alpha-3/beta-1 is a receptor for epiligrin, thrombospondin and CSPG4. Alpha-3/beta-1 may mediate with LGALS3 the stimulation by CSPG4 of endothelial cells migration. Integrin alpha-V/beta-1 is a receptor for vitronectin. Beta-1 integrins recognize the sequence R-G-D in a wide array of ligands. Isoform 2 interferes with isoform 1 resulting in a dominant negative effect on cell adhesion and migration (in vitro). When associated with alpha-7/beta-1 integrin, regulates cell adhesion and laminin matrix deposition. Involved in promoting endothelial cell motility and angiogenesis. Involved in osteoblast compaction through the fibronectin fibrillogenesis cell-mediated matrix assembly process and the formation of mineralized bone nodules. May be involved in up-regulation of the activity of kinases such as PKC via binding to KRT1. Together with KRT1 and RACK1, serves as a platform for SRC activation or inactivation. Plays a mechanistic adhesive role during telophase, required for the successful completion of cytokinesis. Integrin alpha-3/beta-1 provides a docking site for FAP (seprase) at invadopodia plasma membranes in a collagen-dependent manner and hence may participate in the adhesion, formation of invadopodia and matrix degradation processes, promoting cell invasion. ITGA4:ITGB1 binds to fractalkine (CX3CL1) and may act as its coreceptor in CX3CR1-dependent fractalkine signaling (PubMed:23125415, PubMed:24789099). ITGA4:ITGB1 and ITGA5:ITGB1 bind to PLA2G2A via a site (site 2) which is distinct from the classical ligand-binding site (site 1) and this induces integrin conformational changes and enhanced ligand binding to site 1 (PubMed:18635536, PubMed:25398877). ITGA5:ITGB1 acts as a receptor for fibrillin-1 (FBN1) and mediates R-G-D-dependent cell adhesion to FBN1 (PubMed:12807887, PubMed:17158881).
      Isoform 5: Isoform 5 displaces isoform 1 in striated muscles.
      (Microbial infection) Integrin ITGA2:ITGB1 acts as a receptor for human echoviruses 1 and 8 (PubMed:8411387). Acts as a receptor for cytomegalovirus/HHV-5 (PubMed:20660204). Acts as a receptor for Epstein-Barr virus/HHV-4 (PubMed:17945327). Integrin ITGA5:ITGB1 acts as a receptor for human parvovirus B19 (PubMed:12907437). Integrin ITGA2:ITGB1 acts as a receptor for human rotavirus (PubMed:12941907). Acts as a receptor for mammalian reovirus (PubMed:16501085). In case of HIV-1 infection, integrin ITGA5:ITGB1 binding to extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions (PubMed:10397733).
    • Tissue specificity
      Isoform 1 is widely expressed, other isoforms are generally coexpressed with a more restricted distribution. Isoform 2 is expressed in skin, liver, skeletal muscle, cardiac muscle, placenta, umbilical vein endothelial cells, neuroblastoma cells, lymphoma cells, hepatoma cells and astrocytoma cells. Isoform 3 and isoform 4 are expressed in muscle, kidney, liver, placenta, cervical epithelium, umbilical vein endothelial cells, fibroblast cells, embryonal kidney cells, platelets and several blood cell lines. Isoform 4, rather than isoform 3, is selectively expressed in peripheral T-cells. Isoform 3 is expressed in non-proliferating and differentiated prostate gland epithelial cells and in platelets, on the surface of erythroleukemia cells and in various hematopoietic cell lines. Isoform 5 is expressed specifically in striated muscle (skeletal and cardiac muscle).
    • Sequence similarities
      Belongs to the integrin beta chain family.
      Contains 1 VWFA domain.
    • Post-translational
      modifications
      The cysteine residues are involved in intrachain disulfide bonds.
    • Cellular localization
      Cell membrane, sarcolemma. Cell junction. In cardiac muscle, isoform 5 is found in costameres and intercalated disks and Cell membrane. Cell projection, invadopodium membrane. Cell projection, ruffle membrane. Recycling endosome. Melanosome. Cleavage furrow. Cell projection, lamellipodium. Cell projection, ruffle. Cell junction, focal adhesion. Cell surface. Isoform 2 does not localize to focal adhesions. Highly enriched in stage I melanosomes. Located on plasma membrane of neuroblastoma NMB7 cells. In a lung cancer cell line, in prometaphase and metaphase, localizes diffusely at the membrane and in a few intracellular vesicles. In early telophase, detected mainly on the matrix-facing side of the cells. By mid-telophase, concentrated to the ingressing cleavage furrow, mainly to the basal side of the furrow. In late telophase, concentrated to the extending protrusions formed at the opposite ends of the spreading daughter cells, in vesicles at the base of the lamellipodia formed by the separating daughter cells. Colocalizes with ITGB1BP1 and metastatic suppressor protein NME2 at the edge or peripheral ruffles and lamellipodia during the early stages of cell spreading on fibronectin or collagen. Translocates from peripheral focal adhesions sites to fibrillar adhesions in a ITGB1BP1-dependent manner. Enriched preferentially at invadopodia, cell membrane protrusions that correspond to sites of cell invasion, in a collagen-dependent manner. Localized at plasma and ruffle membranes in a collagen-independent manner.

      Question

      Hello, I wanted to ask is this antibody recognizing activated b1 integrins?

      Read More
      Answer

      Yes, it does. Anti-Integrin beta 1 antibody ab30394 [12G10] is conformation-specific, and it recognizes the subset of beta1 integrins with high affinity for ligand (i.e. activated). In fact, it is the best antibody for this purpose because it binds close to the ligand-binding site, and the expression of its epitope is regulated by divalent cations in the same way that ligand binding is regulated.

      For more information about the production and characterization of the antibody, please consult the following reference.

      Question

      Objective: I am interested in one of your R-PE conjugation kit for FACS antibodies.

      Previously, we ordered Integrin B1 antibody ((12G10)(ab30394)) for FACS analysis.

      Because your antibody is a purified one, I plan to conjugate R-PE dye to the antibodies and I found your R-PE conjugation kit (ab 102918).

      I want to know whether I can use your R-PE conjugation kit-produced labeled antibodies directly to the sample
      or I should use extra antibody purification step (such as column purification) before FACS analysis.

      Please let me know ASAP.

      Read More
      Answer

      Thank you for contacting us.

      We have the same integrin beta 1 antibody [12G10] that is FITC conjugated as ab150002, just so you know, but we do not have an R-PE conjugated version.

      But if you would like to conjugate the ab30394 to R-PE using our EasyLink kit ab102918, that would definitely work. Once the antibody is conjugated using the kit, it is ready to use and no further purification is necessary.

      I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

      Can we request a replacement?

      Regards,

      Read More
      Answer

      Thank you very much for your email.

      Looking through our records, it seems we already issued a credit to compensate for the ab30394 that wasn't working, as requested by email in May. The credit note number is ***, and it was probably applied back to the credit card used on the order. Could you confirm with your purchasing department whether this credit was received? They can contact our accounting department at mailto:us.credits@abcam.com or 888-772-2226 if they have any questions. This credit can be applied to the invoice of a new order placed with us, so it will essentially be a replacement antibody of your choice.

      I am very sorry for any confusion regarding this credit note, but please let me know if you have any questions or concerns, and I'll be happy to help you further.

      Question

      I want an antibody that recognizes total integrin B1. I know 12g10 recognizes the active conformation. Which will recognize both active and inactive. Thank you

      Read More
      Answer

      Thank you for contacting us.

      Several of the monoclonals we carry, mouse or rabbit, probably recognize total integrin beta 1, and their affinity is unlikely to be depend on whether an active conformation has been induced by ligand. However, they have not, to our knowledge, been characterized as thoroughly as the 12g10 clone was in this regard. FEBS Lett. 1995 Apr 17;363(1-2):118-22. PMID: 7537221.

      Of the other clones, the rabbit monoclonal ab52971 has been published several times and we have received many positive reviews from customers, Including some western blot reviews that suggest it is specific for an epitope common to several isoforms.

      To be assured that you are detecting total integrin beta 1, I recommend a rabbit polyclonal raised against a larger fragment, as it will detect multiple epitopes that are independent of binding of ligand to the integrin. For example, ab118206:

      Read More
      Answer

      Thank you for contacting Abcam. I have a response from the lab regarding conformational specificity of our Integrin beta 1 products.

      ab30394 Anti-Integrin beta 1 antibody [12G10]is conformation-specific, and it recognizes the subset of beta1 integrins with high affinity for ligand (i.e. activated). In fact, it is the best antibody for this purpose because it binds close to the ligand-binding site, and the expression of its epitope is exquisitely regulated by divalent cations in the same way that ligand binding is regulated. More information about ab30394 may be found at: https://www.abcam.com/Integrin-beta-1-antibody-12G10-ab30394.html
