Scientific Background: Brk (PTK6) is a protein-tyrosine kinase of the TK group and Src family. It is a non-receptor kinase that is implicated as a regulator of several intracellular signalling pathways involved in cellular differentiation, epithelial maintenance, and tumourigenesis. The activity of Brk appears to be dependent upon the cell type and intracellular localization of the protein. In non-tumour cells, Brk activity promotes cellular differentiation and apoptosis, while in cancer tissue Brk activity sensitizes cells to growth promoting signals leading to increased cell proliferation, anchorage-independent cell survival, and cell migration/invasion. The nuclear form of the protein is thought to be involved in regulating epithelial growth. The 451-amino acid sequence of the Brk protein resembles that of a Src family kinase, containing a SH3, SH2, and a catalytic domain. However unlike Src kinases, the N-terminal domain of the Brk protein does not contain a myristolyation domain, indicating different regualtory mechanisms. Brk mRNA is expressed at high levels in the colon, small intestine, and prostate as well as at low levels in some fetal tissues.
