Sos2

Enables guanyl-nucleotide exchange factor activity. Involved in insulin receptor signaling pathway. Acts upstream of or within several processes, including B cell homeostasis; regulation of T cell activation; and regulation of pro-B cell differentiation. Predicted to be active in plasma membrane. Is expressed in several structures, including extraembryonic component; genitourinary system; hemolymphoid system gland; 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). [provided by Alliance of Genome Resources, Jul 2025]

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Sos2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
