Biochem/physiol Actions

BRK is a member of the non-receptor tyrosine kinases (PTKs) that contains an amino terminal SH3 and SH2 domain as well as the catalytic domain. BRK expression is low or undetectable in normal mammary tissue and benign lesions. However, approximately two-thirds of breast tumors express appreciable levels and 27% of tumors over express BRK by fivefold or more.

Physical form

Supplied in 50 mM Tris-HCl, pH 7.5, with 150 mM NaCl, 0.2 5mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, and 25% glycerol.

Oncogene, 15(12), 1497-1502 (1997-10-23)
The brk gene encodes a non-receptor protein tyrosine kinase that consists of single SH3, SH2 and catalytic domains. Although BRK shows strongest sequence similarity to members of the SRC family of PTKs, there are several key structural and regulatory differences
P J Mitchell et al.
Oncogene, 9(8), 2383-2390 (1994-08-01)
Using a polymerase chain reaction based differential screening approach, we have isolated and characterised a cDNA from a human metastatic breast tumour representing a novel protein tyrosine kinase (brk). Sequencing of brk cDNAs isolated from T-47D and MCF-7 human breast
