Summary

SRMS (src-related kinase lacking C-terminal regulatory tyrosine and N-terminal myristylation sites, HGNC:11298) is a protein-coding gene on chromosome 20q13.33, encoding Tyrosine-protein kinase Srms (Q9H3Y6). Non-receptor tyrosine-protein kinase which phosphorylates DOK1 on tyrosine residues.

Enables protein tyrosine kinase activity. Involved in peptidyl-tyrosine autophosphorylation and positive regulation of TORC1 signaling. Located in cytoplasm.

UniProt curated annotations — full annotation on UniProt →

Function. Non-receptor tyrosine-protein kinase which phosphorylates DOK1 on tyrosine residues. Also phosphorylates KHDRBS1/SAM68 and VIM on tyrosine residues. Phosphorylation of KHDRBS1 is EGF-dependent. Phosphorylates OTUB1, promoting deubiquitination of RPTOR.

Subunit / interactions. Interacts (via the SH2 and SH3 domains) with DOK1. Interacts with KHDRBS1/SAM68 and VIM.

Subcellular location. Cytoplasm.

Tissue specificity. Highly expressed in most breast cancers (at protein level).

Domain organisation. The N-terminal region regulates its kinase activity.

Similarity. Belongs to the protein kinase superfamily. Tyr protein kinase family. SRC subfamily.
