Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nThe Bcr gene was orginally identified by its presence in the chimeric Bcr-Abl oncogene (1). The amino-terminal region of Bcr contains an oligomerization domain, a serine\/threonine kinase domain, and a region that binds SH2 domains. The middle of the protein has a PH domain and a region of sequence similarity to the guanine nucleotide exchange factors for the Rho family of GTP binding proteins. The carboxy-terminal region may be involved in a GTPase activating function for the small GTP-binding protein Rac (2,3). The function of wild type Bcr in cells remains unclear. PDGF receptor may use Bcr as a downstream signaling mediator (4). Research studies have shown that the Bcr-Abl fusion results in production of a constitutively active tyrosine kinase, which causes chronic myelogenous leukemia (CML) (5). Tyr177 of Bcr is phosphorylated in the Bcr-Abl fusion protein, which plays an important role in transforming the activity of Bcr-Abl (6). Phosphorylated Tyr177 provides a docking site for Gab2 and GRB2 (7,8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nALL; BCR; BCR activator of RhoGEF and GTPase; BCR, RhoGEF and GTPase activating protein; BCR\/FGFR1 chimera protein; BCR1; breakpoint cluster region; Breakpoint cluster region protein; CML; D22S11; D22S662; FGFR1\/BCR chimera protein; FLJ16453; PHL; Renal carcinoma antigen NY-REN-26\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Pg\nSENSITIVITY: Endogenous\nMW (kDa): 130, 160 (Bcr); 210 (Bcr-Abl)\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799467839657,"sku":"3902S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3902s","provider":"Iright","version":"1.0","type":"link"}
