Human LARG Antibody

LARG (Leukemia-associated RhoGEF, also known as Rho guanine nucleotide exchange factor 12) is a 173 kDa member of the DH‑domain containing RhoGEF family of molecules. It is ubiquitously expressed, and known to interact with semaphorin-activated B class plexins, thereby activating Rho-dependent pathways. Human LARG is 1544 amino acids (aa) in length. It contains one PZD domain that binds to plexin (aa 72‑151), an RGSL region (aa 368‑558), and a RhoGEF domain (aa 788‑975). There are at least two potential splice forms. One shows a deletion of aa 48‑66 with an 8 aa poly-Lys substitution for the C-terminal 960 amino acids. A second shows an insertion of 9 aa between Thr1093 and Asp1094, accompanied by a 6 aa substitution for the C-terminal 131 amino acids. Over aa 154‑575, human LARG is 90% aa identical to mouse LARG.
