Function

[SRC_RSVSA] This phosphoprotein, required for both the initiation and the maintenance of neoplastic transformation, is a protein kinase that catalyzes the phosphorylation of tyrosine residues in vitro. [MT_POVHA] Plays a role in transformation by modulating the activities of cellular proteins involved in control of cell proliferation and by acting as a functional homolog of an activated tyrosine kinase-associated growth-factor receptor. Recruits upon association with Ppp2/PP2A the Src tyrosine kinase component Fyn, thereby activating its kinase activity. In turn, MT becomes phosphorylated and mediates signal transduction pathways leading to cell cycle progression and cell division. MT plays also a role in regulation of early and late gene expression as well as viral DNA replication (By similarity).

Publication Abstract from PubMed

The crystal structure of the Src SH2 domain complexed with a high affinity 11-residue phosphopeptide has been determined at 2.7 A resolution by X-ray diffraction. The peptide binds in an extended conformation and makes primary interactions with the SH2 domain at six central residues: PQ(pY)EEI. The phosphotyrosine and the isoleucine are tightly bound by two well-defined pockets on the protein surface, resulting in a complex that resembles a two-pronged plug engaging a two-holed socket. The glutamate residues are in solvent-exposed environments in the vicinity of basic side chains of the SH2 domain, and the two N-terminal residues cap the phosphotyrosine-binding site. The crystal structure of Src SH2 in the absence of peptide has been determined at 2.5 A resolution, and comparison with the structure of the high affinity complex reveals only localized and relatively small changes.
