Tyrosine-protein kinase 6 is an enzyme that in humans is encoded by the PTK6 gene.[5][6][7]

Function[edit]

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.[7]

Clinical significance[edit]

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.[7]

Interactions[edit]

PTK6 has been shown to interact with STAP2[8] and KHDRBS1.[9]
