Overview
Src proto-oncogenic cytoplasmic tyrosine kinase of the SRC family. Highly expressed in certain fully differentiated cells such as neurons, platelets and macrophages. Phosphorylation of an activation loop tyrosine activates the enzyme; phosphorylation of a tyrosine in the C-terminus by Csk inhibits the enzyme. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
Protein type: Protein kinase, TK; Kinase, protein; Protein kinase, tyrosine (non-receptor); EC 2.7.10.2; TK group; Src family
Chromosomal Location of Human Ortholog: 20q12-q13
Cellular Component: cytoskeleton; mitochondrion; lysosome; mitochondrial inner membrane; cytoplasm; late endosome; plasma membrane; caveola; nucleus; cytosol
Molecular Function: identical protein binding; ephrin receptor binding; non-membrane spanning protein tyrosine kinase activity; phosphoprotein binding; protein kinase activity; integrin binding; protein binding; SH3/SH2 adaptor activity; protein-tyrosine kinase activity; heme binding; kinase activity; SH2 domain binding; ATP binding; receptor binding
Biological Process: oogenesis; regulation of estrogen receptor signaling pathway; axon guidance; progesterone receptor signaling pathway; peptidyl-tyrosine phosphorylation; viral reproduction; nerve growth factor receptor signaling pathway; protein amino acid autophosphorylation; negative regulation of caspase activity; signal transduction; uterus development; negative regulation of mitochondrial depolarization; negative regulation of protein homooligomerization; forebrain development; cell adhesion; bone resorption; epidermal growth factor receptor signaling pathway; platelet activation; regulation of bone resorption; fibroblast growth factor receptor signaling pathway; negative regulation of focal adhesion formation; signal complex assembly; cell cycle; positive regulation of integrin activation; positive regulation of protein kinase B signaling cascade; regulation of protein binding; Ras protein signal transduction; T cell costimulation; innate immune response; regulation of vascular permeability; blood coagulation; leukocyte migration; negative regulation of apoptosis
