c-Src (proto-oncogene tyrosine-protein kinase Src) is a 60 kDa tyrosine protein kinase that contains both SH2 and SH3 domains. c-Src is a lipid-modified signaling molecule (myristoylated) involved in cell-cell interactions, cell migration and proliferation through the phosphorylation of many substrates. c-Src is expressed at high levels in differentiated cells including neurons, platelets and macrophages, and can be activated by phospholipase D, insulin-like growth factor receptor, EGF-receptor, fibroblast growth factor receptor and prolactin receptor binding. c-Src can be phosphorylated on multiple sites to interact with polyoma virus middle T antigen, PYK2, HSP72 and caveolin, and efficient study methods are in high demand.
