Kinase Family CCK4

Kinase Classification: Group TK: Family CCK4

These receptor tyrosine kinases uniquely recognize and signal downstream of extracellular collagen.

Evolution

TAMs are vertebrate-specific, with three members in tetrapods and four in most fish. A possible TAM has been seen in the invertebrate chordate, Ciona intestinalis.

Domain Structure

TAMS are single-pass transmembrane proteins, with extracellular Ig and FN3 domains, and an intracellular tyrosine kinase domain.
