Human SIRP Beta 1 isoform 3 Protein

Recombinant Human SIRP Beta 1 isoform 3 Proteinis expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Glu30-Leu371. Signal regulatory protein beta1 (SIRPB1) is a signal regulatory protein member of the immunoglobulin superfamily and is capable of modulating receptor tyrosine kinase-coupled signaling. Copy number variations at the SIRPB1 locus were previously reported to associate with prostate cancer aggressiveness in patients.SIRPB1 gene amplification and overexpression were detected in prostate cancer specimens. The knockdown of SIRPB1 significantly suppressed cell growth in colony formation assays and cell mobility.
