  • Target

    • Function

      Involved in calcium induced regulation of ion channel and activation of the map kinase signaling pathway. May represent an important signaling intermediate between neuropeptide activated receptors or neurotransmitters that increase calcium flux and the downstream signals that regulate neuronal activity. Interacts with the SH2 domain of Grb2. May phosphorylate the voltage-gated potassium channel protein Kv1.2. Its activation is highly correlated with the stimulation of c-Jun N-terminal kinase activity. Involved in osmotic stress-dependent SNCA 'Tyr-125' phosphorylation. In concert with SRC, plays an important role in osteoclastic bone resorption. Both the formation of a SRC-PTK2B complex, and SRC kinase activity are necessary for this function. The Tyr-402 phosphorylated form serves as a docking site for SRC and is important for the organization of the osteoclast actin cytoskeleton and attachment sites and for bone resorption.
    • Tissue specificity

      Most abundant in the brain, with highest levels in amygdala and hippocampus. Low levels in kidney. Also expressed in spleen and lymphocytes.
    • Sequence similarities

      Belongs to the protein kinase superfamily. Tyr protein kinase family. FAK subfamily.
      Contains 1 FERM domain.
      Contains 1 protein kinase domain.
    • Post-translational
      modifications

      Phosphorylated on tyrosine residues in response to various stimuli that elevate the intracellular calcium concentration, as well as by PKC activation. Recruitment by nephrocystin to cell matrix adhesions initiates Tyr-402 phosphorylation. In monocytes, adherence to substrata is required for tyrosine phosphorylation and kinase activation. Angiotensin II, thapsigargin and L-alpha-lysophosphatidic acid (LPA) also induce autophosphorylation and increase kinase activity.
    • Cellular localization

      Cytoplasm. Cell membrane. Interaction with nephrocystin induces the membrane-association of the kinase.

        Peptide Competition: Extracts prepared from CEF cells expressing Pyk2 and plated on fibronectin were resolved by SDS-PAGE on a 10% Tris glycine gel. The proteins were then transferred to nitrocellulose. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4oC, then were incubated with 0.50 µg/mL ab4800 antibody, following prior incubation with: no peptide (1), the non-phosphopeptide corresponding to phosphopeptide immunogen (2), a generic phosphotyrosine containing peptide (3), the phosphopeptide corresponding to tyrosine 397 on FAK (4), or, the phosphopeptide immunogen (5). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and bands were detected using the Tropix WesternStar method. The data show that only the phosphopeptide corresponding to this site blocks the antibody signal, therefore demonstrating the specificity of ab4800 antibody for this phosphorylated residue.

      Answer

      Thank you for contacting us and your interest in our products. I am sorry for the delay in getting back to you.

      As we discussed over the phone, I have looked into how the Anti-PYK2 (phospho Y402) antibodies ab4800 and ab131543 have been characterized for their potential cross-reactivity with other phospho-proteins.

      No specific experiments have been carried out to ascertain the cross-reactivity of either of these antibodies. However, the western results are based on total cell lysates which contains thousands of other proteins many of which are phosphorylated. As the Western blot images for these antibodies show, only one band was detected in the molecular range from 37 kDa up to 250 kDa, there is no other visible band.

      In addition, with ab4800 the target band was competed out with the phosphorylated immunogen peptide indicating the band we see is the targe Pyk2 pY402. This supports at least in the cells (primary CDF cells, and SDF-1a treated Reh cells) we studied we did not see any cross reactivity with other proteins (phosphorylated or not phosphorylated).

      From blast search of the immunogens used, the area does not seem to share homology with any other protein (that have been added to this databank) suggesting there should not be any cross-reactivity observed.

      Question

      Hi,   I have technical questions regarding 2 of your products: PYK2 protein (Active), cat. no ab60878, and PYK2 protein (His tag), cat. no ab42622.   I need to know the phosphorylation site of these 2 proteins. More specifically, I need to know if these proteins are phosphorylated at Tyrosine 402.

      Asked on May 18 2012

      Answer

      Thank you for contacting us. I do want to apologize for the tardiness of this response.

      I have been in contact with the originator labs for ab42622 and ab60878 PYK2 proteins, in regards to whether these products are phosphorylated at Y402. Unfortunately neither group was able to confirm whether Y402 is phosphorylated at this site and each recommended that phophorylation state may be determined by performing a western blot with a phospho specific antibody such as ab4800 (https://www.abcam.com/PYK2-phospho-Y402-antibody-ab4800.html).

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

      Question

      I am interested in ab4800, the Pyk2 phospho Y402 antibody. We would like to use it on mouse pituitary glands. Can you tell me if this antibody works with paraffin-embedded sections? If not under what conditions might it work in tissues rather than cells (your references on the web site are all cells)?

      Asked on Mar 29 2004

      Answer

      Thank you for your enquiry. Ab4800 was tested in IHC cryostat sections in the following reference: Melendez J. et al (2002) J. Biol. Chem. 277(47):45203-45210. The authors prepared mouse heart sections fixed in 4% paraformaldehyde/PBS overnight at 4 degrees C. The next day, the hearts were subjected to progressive sucrose gradient from 10%, 20%, 30% at 4 degrees C for 1 hour at each step. Embedded in Tisse-Tek, frozen in melting isopentane floated above liquid nitrogen, and frozen blocks were stored at -80 degrees C Section 7 microns thick were mounted on Superfrost slides (Fisher Scientific Co), allowed to dry, and then stored at 4 degrees C until used within 1 week. For labeling, primary antibodies were applied to the sections and left overnight. The next day, the sections were washed, secondary antibodies applied to the sections for 1 hour, washed again, and then mounted in Vectashield (Vecyor Laboratories). Primary antibodies were detected by fluorescent secondary goat anti-rabbit IgG. We recommend using the antibody at ~1:50 dilution to 1:100 dilution. If you have any more questions, please contact us again.
