Recombinant full-lengthhuman cytoplasmic tyrosine-proteinkinase BMX (BMX), also known as bonemarrow tyrosine kinase gene inchromosome X protein, epithelial andendothelial tyrosine kinase, ETK, andNTK38 was expressed by baculovirus inSf9 insect cells using an N-terminal GSTtag, a.a. 1-675 (end). The geneaccession number is NM_001721(variant 2).
Host cell line: Sf9 cells
Specific activity: 43 pmol/min/ug
Background
The BMX gene encodes a non-receptor tyrosine kinase, which may play a role in the growth and differentiation of hematopoietic cells (1). The BMX gene is located on chromosomal band Xp22.2 between the DXS197 and DXS207 loci. Interestingly, chromosome X also contains the closest relative of BMX, the BTK gene, implicated in X-linked agammaglobulinemia. BMX, is found to induce activation of the Stat signaling pathway (2).
