Application

SRC, active, GST tagged human has been used in the in vitro kinase assay.

Biochem/physiol Actions

SRC proto-oncogene, non-receptor tyrosine kinase (SRC) phosphorylates membrane proteins and nucleoproteins and activates various intracellular signaling cascades. It is overexpressed and activated in a large number of human malignancies and has been linked to the development of cancer and progression to distant metastases. In addition to increasing cell proliferation, a key role of SRC in cancer seems to be the ability to promote invasion and motility, functions that might contribute to tumor progression.

General description

SRC proto-oncogene, non-receptor tyrosine kinase (SRC) belongs to the family of non-receptor tyrosine kinases. SRC was originally identified as a transforming protein of the Rous sarcoma virus (RSV) that had enzymatic ability to phosphorylate tyrosine in protein substrates. It contains an amino-terminal domain, conserved Src-homology domains (SH2 and SH3), a tyrosine kinase domain and the carboxyl-terminus. The gene encoding this protein is localized on human chromosome 20q11.23.
