  • Function

    Non-receptor protein tyrosine kinase that plays pivotal roles in numerous cellular processes such as proliferation, migration, and transformation. In concert with PTK2B, 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. Once it is recruited to the activated integrins, by PTK2B, it phosphorylates CBL which in turn induces the activation and recruitment of phosphatidylinositol 3-kinase to the cell membrane in a signaling pathway that is critical for osteoclast function. Promotes energy production in osteoclasts by activating mitochondrial cytochrome C oxidase. Phosphorylates RUNX3 and COX2 on tyrosine residues, TNK2 on 'Tyr-284' and CBL on 'Tyr-731'. Enhances DDX58/RIG-I-elicited antiviral signaling.
  • Sequence similarities

    Belongs to the protein kinase superfamily. Tyr protein kinase family. SRC subfamily.
    Contains 1 protein kinase domain.
    Contains 1 SH2 domain.
    Contains 1 SH3 domain.
  • Post-translational

    Dephosphorylated at Tyr-530 by PTPRJ (By similarity). Phosphorylated on Tyr-530 by c-Src kinase (CSK). The phosphorylated form is termed pp60c-src. Dephosphorylated by PTPRJ at Tyr-419. Normally maintained in an inactive conformation with the SH2 domain engaged with Tyr-530, the SH3 domain engaged with the SH2-kinase linker, and Tyr-419 dephosphorylated. Dephosphorylation of Tyr-530 as a result of protein tyrosine phosphatase (PTP) action disrupts the intramolecular interaction between the SH2 domain and Tyr-530, Tyr-419 can then become autophosphorylated, resulting in SRC activation. Phosphorylation of Tyr-530 by CSK allows this interaction to reform, resulting in SRC inactivation.
    S-nitrosylation is important for activation of its kinase activity.
  • Cellular localization

    Cell membrane. Mitochondrion inner membrane.

Thank you for your reply and the additional information which is very helpful. The fact that the total protein gives you the same band pattern might indicate that these bands could be real for your rat samples. Which antibody did you use to detect total Src? Rat is listed as "predicted to work with" on the datasheet which means that it is only predicted based on sequence homology for the immunogen. We have no data for rat samples so far and do not know if and how well it would work with this species. Does the treatment to inactivate Src give you the expected results (increase/decrease in signal)? The total protein should nevertheless remain unchanged as the total protein should not be affected by changes in phosphorylation. Do you see this as well? I'd be happy to issue you a testing discount retroactively since you are using the antibody on an untested species. The discount code will give you a free antibody on a future purchase after the rat data have been submitted as an Abreview. Here are more details on how this works: For UNTESTED species and/or applications, we have established a testing discount program. The testing discount program is for customers who like to use an antibody/protein on an untested species/application. You would purchase the antibody at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody at the full price (100%) of the antibody you have tested. The terms and conditions applicable to this offer can be found here: https://www.abcam.com/collaborationdiscount. Please let me know if I shall send you a discount code. I look forward to hear back from you.

Thank you for contacting us and for including the WB image. The band shown on our datasheet runs at about 55 to 60 kDa and was blocked with the immunizing peptide. Only human samples have so far been tested with this antibody. This antibody detects phospho-Src. What does your total protein sample look like? And have you tried any other sample (e.g. human sample or cell line)? What antibody dilution are you using? And what are the blocking conditions? I am not quite certain what the 85 kDa band could be. The protein can be potentially phosphorylated at multiple sites, and depending on the location of the phospho-site (e.g. in proximity to a Proline residue) the MW can sometimes shift to a higher MW than expected. But since we have not tried rat samples, I am not sure if this band pattern is sample specific or species specific or if the antibody gives extra (non-specific?) bands in rat samples. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
