Automated description from the Alliance of Genome Resources (Release 3.2)
Exhibits Ras guanyl-nucleotide exchange factor activity. Involved in several processes, including B cell homeostasis; regulation of T cell activation; and regulation of pro-B cell differentiation. Predicted to localize to nucleosome. Is expressed in several structures, including genitourinary system; hemolymphoid system gland; intestine; liver; and lung. Human ortholog(s) of this gene implicated in Noonan syndrome 9. Orthologous to human SOS2 (SOS Ras/Rho guanine nucleotide exchange factor 2).
