製品の詳細Rabbit polyclonal to Src (phospho Y418)
アプリケーション適用あり: IHC-P, WBmore details
種交差性交差種: Mouse, Chicken, Human
Synthetic peptide derived from the region of Src that contains tyrosine 418 (tyrosine 419 including the initiating methionine). The sequence is conserved in human, mouse, rat, chicken and frog.
Src (also known as pp60src) is a non-receptor tyrosine kinase involved in signal transduction in many biological systems and implicated in the development of human tumors. Tyrosine 418 is located in the catalytic domain and is one of the autophosphorylation sites. Full catalytic activity of Src requires phosphorylation of tyrosine 418 (tyrosine 414 on frog Src, tyrosine 416 on chicken Src, and tyrosine 424 on mouse Src). This region of Src is also highly conserved in all of the related Src-family kinases, and thus prior immunoprecipitation may be required to identify which Src family member is being activated.
Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

精製度Immunogen affinity purified
特記事項（精製）Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively pre-adsorbed using (i) a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated Src, and (ii) a generic tyrosine phosphorylated peptide to remove antibody that is reactive with phosphotyrosine, irrespective of the sequence. The final product is generated by affinity chromatography using a Src-derived peptide that is phosphorylated at tyrosine 418.

機能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.

翻訳後修飾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.

Immunohistochemical analysis of paraffin embedded Human colon carcinoma, labelling Src with ab4816. A negative control without ab4816 is shown on the left. Antigen retrieval performed using 10mM sodium citrate, microwaved for 8-15mins, blocked using 3% H2O2-methanol, then treated with ab4816 followed by an HRP-conjugated secondary antibody. Counterstaining with hematoxylin.
Western blot detection of Src phosphorylation in extracts of chick embryo fibroblasts expressing wild-type (lanes 2,4,6) or mutant (lanes 1,3,5) pp60src. Truncation of Src at position 518 eliminated phosphorylation at the negative regulatory site [pY529], while increasing phosphorylation at the catalytic site [pY418].
