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

Contents

Function

Tyrosine-protein kinase 6—also known as BRK [7] (breast tumor kinase)—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

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

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