Tyrosine-protein kinase 6 is an enzyme that in humans is encoded by the PTK6 gene.[1][2][3]

Function

Tyrosine-protein kinase 6 (also known as Breast Tumor Kinase, Brk) is a cytoplasmic non-receptor protein kinase which may function as an intracellular signal transducer in epithelial tissues. The encoded protein has been shown to undergo autophosphorylation.[3]

Clinical significance

Overexpression of this gene in mammary epithelial cells leads to sensitization of the cells to epidermal growth factor and results in a partially transformed phenotype. Expression of this gene has been detected at low levels in some breast tumors but not in normal breast tissue.[3]

Interactions

PTK6 has been shown to interact with STAP2[4] and KHDRBS1.[5]
