|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 77 kDa (predicted molecular weight: 77 kDa).|
|IHC-Fr||Use a concentration of 5 µg/ml.|
FunctionInvolved in cell adhesion. Contributes to integrin activation. When coexpressed with talin, potentiates activation of ITGA2B. Required for normal keratinocyte proliferation. Required for normal polarization of basal keratinocytes in skin, and for normal cell shape. Required for normal adhesion of keratinocytes to fibronectin and laminin, and for normal keratinocyte migration to wound sites. May mediate TGF-beta 1 signaling in tumor progression.
Tissue specificityExpressed in brain, skeletal muscle, kidney, colon, adrenal gland, prostate, and placenta. Weakly or not expressed in heart, thymus, spleen, liver, small intestine, bone marrow, lung and peripheral blood leukocytes. Overexpressed in some colon and lung tumors. In skin, it is localized within the epidermis and particularly in basal keratocytes. Not detected in epidermal melanocytes and dermal fibroblasts.
Involvement in diseaseDefects in FERMT1 are the cause of Kindler syndrome (KINDS) [MIM:173650]. An autosomal recessive skin disorder characterized by skin blistering, photosensitivity, progressive poikiloderma, and extensive skin atrophy. Additional clinical features include gingival erosions, ocular, esophageal, gastrointestinal and urogenital involvement, and an increased risk of mucocutaneous malignancy. Note=Although most FERMT1 mutations are predicted to lead to premature termination of translation, and to loss of FERMT1 function, significant clinical variability is observed among patients. There is an association of FERMT1 missense and in-frame deletion mutations with milder disease phenotypes, and later onset of complications (PubMed:21936020).
Sequence similaritiesBelongs to the kindlin family.
Contains 1 FERM domain.
Contains 1 PH domain.
DomainThe FERM domain is not correctly detected by PROSITE or Pfam techniques because it contains the insertion of a PH domain. The FERM domain contains the subdomains F1, F2 and F3. It is preceded by a F0 domain with a ubiquitin-like fold. The F0 domain is required for integrin activation and for localization at focal adhesions.
Cellular localizationCytoplasm > cytoskeleton. Cell junction > focal adhesion. Cell projection > ruffle membrane. Constituent of focal adhesions. Localized at the basal aspect of skin keratinocytes, close to the cell membrane. Colocalizes with filamentous actin. Upon TGFB1 treatment, it localizes to membrane ruffles.

IHC image of Kindlin-1 staining in human liver carcnioma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab68041, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

ICC/IF image of ab68041 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab68041, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
ab68041 staining Kindlin-1 in adult mouse uterus tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde, permeabilized with PBST (PBS / 0.1% v/v Triton X-100) and blocked with 3% donkey serum / 1% BSA in PBST for 1 hour at 25°C. Samples were incubated with primary antibody (5µg/ml in 1% BSA / 3% donkey serum in PBST) for 48 hours at 25°C. An Alexa Fluor® 488-conjugated donkey anti-rabbit IgG polyclonal (1/1000) was used as the secondary antibody.
Kindlin-1 positive staining was detected in cells in the epithelial lining of the uterus. Image shows DAPI counterstain, red field (autofluorescence), antibody staining and overlay.
