| src | <molecular biology> The transforming (sarcoma inducing) gene of Rous sarcoma virus. The protein product is pp60vsrc, a cytoplasmic protein with tyrosine specific protein kinase activity, that associates with the cytoplasmic face of the plasma membrane. (12 Jan 1998) |
|---|---|
| src homology domains | Regions of sequence similarity in the src family of cytoplasmic tyrosine kinases. The sh1 domain is a catalytic domain. Sh2 and sh3 domains are protein-binding domains. Sh2 usually binds phosphotyrosine-containing proteins and sh3 interacts with cytoskeletal proteins. (12 Dec 1998) |
| src-family kinases | <enzyme> Family of non-receptor protein-tyrosine kinases homologous to src. They are closely related intracellular enzymes that participate in signal transduction pathways in a variety of haemopoietic cells and especially their surface receptors. Registry number: EC 2.7.1.- (12 Dec 1998) |
| src-related intestinal kinase | <enzyme> An intracellular epithelial cell tyrosine kinase; shares 80% homology with human tyrosine kinase brk; has 451 amino acid residues; amino acid sequence given in first source Registry number: EC 2.7.1.- Synonym: sik protein, sik gene product (26 Jun 1999) |
| beta-cell src-homology tyrosine kinase | <enzyme> A murine frk (fyn-related kinase) homolog; genbank l36132; do not confuse with brain-specific kinase bsk Registry number: EC 2.7.1.- Synonym: beta-cell sh tk, bsk protein, sh tk, bsk gene product, sh tk (26 Jun 1999) |

| genes, src | Retrovirus-associated DNA sequences (src) originally isolated from the rous sarcoma virus (rsv). The proto-oncogene src (c-src) codes for a protein that is a member of the tyrosine kinase family and was the first proto-oncogene identified in the human genome. The human c-src gene is located at 20q12-13 on the long arm of chromosome 20. (12 Dec 1998) |
| proto-oncogene protein pp60(c-src) | <enzyme> Membrane-associated tyrosine-specific kinase encoded by the c-src genes. It has an important role in cellular growth control. Truncation of carboxy-terminal residues in pp60(c-src) leads to pp60(v-src) which has the ability to transform cells. This kinase pp60 c-src should not be confused with csk, also known as c-src kinase. Registry number: EC 2.7.1.- (12 Dec 1998) |
| oncogene protein pp60(v-src) | <chemical> Tyrosine-specific protein kinase encoded by the v-src oncogene of rous sarcoma virus. The transforming activity of pp60(v-src) depends on both the lack of a critical carboxy-terminal tyrosine phosphorylation site at position 527, and the attachment of pp60(v-src) to the plasma membrane which is accomplished by myristylation of its n-terminal glycine. Chemical name: Kinase (phosphorylating), protein pp60src (12 Dec 1998) |
