Automated description from the Alliance of Genome Resources
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 the nucleosome. Human ortholog(s) of this gene implicated in Noonan syndrome 9. Is expressed in several structures, including genitourinary system; hemolymphoid system gland; intestine; liver; and lung. Orthologous to human SOS2 (SOS Ras/Rho guanine nucleotide exchange factor 2).
