What is Src in cells?
Proto-oncogene tyrosine-protein kinase Src, also known as proto-oncogene c-Src, or simply c-Src (cellular Src; pronounced “sarc”, as it is short for sarcoma), is a non-receptor tyrosine kinase protein that in humans is encoded by the SRC gene.
What is the main function of Src?
Src is a non-receptor protein tyrosine kinase that transduces signals that are involved in the control of a variety of cellular processes such as proliferation, differentiation, motility, and adhesion.
Where is Src found in the cell?
Although the normal function of Src still remains largely unclear at present, it has been found to associate with cellular membranes, in particular the plasma membrane, the perinuclear membrane and endosomal membranes (Willingham et al., 1979; Courtneidge et al., 1980; Resh and Erikson, 1985; David Pfeuty and Nouvian- …
What is V SRC and c-Src?
v-Src is therefore an instructive example of an oncogene whereas c-Src is a proto-oncogene. The first sequence of v-Src was published in 1980 and the characterization of sites for tyrosine phosphorylation in the transforming protein of Rous sarcoma virus and its normal cellular homologue was published in 1981.
What is the structure of Src?
From the N- to C-terminus, Src contains an N-terminal 14-carbon myristoyl group, a unique segment, an SH3 domain, an SH2 domain, a protein-tyrosine kinase domain, and a C-terminal regulatory tail.
Is SRC a kinase?
Src kinase family is a family of non-receptor tyrosine kinases that includes nine members: Src, Yes, Fyn, and Fgr, forming the SrcA subfamily, Lck, Hck, Blk, and Lyn in the SrcB subfamily, and Frk in its own subfamily.
What is SRC in virology?
v-Src is a gene found in Rous sarcoma virus (RSV) that encodes a tyrosine kinase that causes a type of cancer in chickens. Tyrosine-protein kinase transforming protein Src. Identifiers. Organism.

What is the role of tyrosine kinases?
Tyrosine kinases are important mediators of this signal transduction process, leading to cell proliferation, differentiation, migration, metabolism and programmed cell death. Tyrosine kinases are a family of enzymes, which catalyzes phosphorylation of select tyrosine residues in target proteins, using ATP.
