Target description

Ras-related C3 botulinum toxin substrate 1 (UniProt: P63000; also known as EC:3.6.5.2, Cell migration-inducing gene 5 protein, Ras-like protein TC25, p21-Rac1) is encoded by the RAC1 (also known as TC25, MIG5) gene (Gene ID: 5879) in human. Rac1 is a plasma membrane-associated small GTPase that cycles between active GTP-bound and inactive GDP-bound states. In its active state, it binds to a variety of effector proteins to regulate cellular responses. Two isoforms of Rac1 have been described that are produced by alternative splicing. Rac1b differs from Rac1a in that it has an additional 19 amino acids and is found in various tumors, such as breasts and colorectal. Rac1b has an accelerated GEF-independent GDP/GTP exchange and an impaired GTP hydrolysis, which is restored partially by GTPase-activating proteins. It can bind to the GTPase-binding domain of PAK, but not full-length PAK in a GTP-dependent manner, suggesting that the insertion does not completely abolish effector interaction. Isoform B is predominantly identified in skin and epithelial tissues from the intestinal tract. Its expression is elevated in colorectal tumors at various stages of neoplastic progression, as compared to their respective adjacent tissues. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
