SRC
This gene is highly similar to the v-src gene of Rous sarcoma virus. This proto-oncogene may play a role in the regulation of embryonic development and cell growth. The protein encoded by this gene is a tyrosine-protein kinase whose activity can be inhibited by phosphorylation by c-SRC kinase. Mutations in this gene could be involved in the malignant progression of colon cancer. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

Cellular Location
Cell membrane
Mitochondrion inner membrane
Nucleus
Cytoplasm, cytoskeleton
Cytoplasm, perinuclear region
Cell junction, focal adhesion
Localizes to focal adhesion sites following integrin engagement (PubMed:22801373).
Localization to focal adhesion sites requires myristoylation and the SH3 domain (PubMed:7525268).
Colocalizes with PDLIM4 at the perinuclear region, but not at focal adhesions (PubMed:19307596).
Involvement in disease
Thrombocytopenia 6 (THC6):
A form of thrombocytopenia, a hematologic disorder defined by a decrease in the number of platelets in circulating blood, resulting in the potential for increased bleeding and decreased ability for clotting. THC6 is an autosomal dominant form. Affected individuals may also have bone abnormalities and an increased risk for myelofibrosis.
PTM
Myristoylated at Gly-2, and this is essential for targeting to membranes.
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. CDK5-mediated phosphorylation at Ser-75 targets SRC to ubiquitin-dependent degradation and thus leads to cytoskeletal reorganization. Phosphorylated by PTK2/FAK1; this enhances kinase activity. Phosphorylated by PTK2B/PYK2; this enhances kinase activity. Upon activation of IL6ST by IL6, Tyr-419 is phosphorylated and Tyr-530 dephosphorylated (PubMed:25731159).
Isoform 1
Displays reduced levels of autophosphorylation at Tyr-419 compared to isoforms 2 and 3.
Isoform 2
Displays enhanced levels of autophosphorylation at Tyr-419 compared to isoform 1.
Isoform 3
Displays enhanced levels of autophosphorylation at Tyr-419 compared to isoform 1 (By similarity).
Shows reduced phosphorylation at Tyr-527 compared to isoforms 1 and 2 (By similarity).
S-nitrosylation is important for activation of its kinase activity.
Ubiquitinated in response to CDK5-mediated phosphorylation. Ubiquitination mediated by CBLC requires SRC autophosphorylation at Tyr-419 and may lead to lysosomal degradation.
