Gnb1 Gene Summary [Mouse]
Predicted to enable several functions, including GTPase binding activity; alkylglycerophosphoethanolamine phosphodiesterase activity; and spectrin binding activity. Acts upstream of or within several processes, including phospholipase C-activating G protein-coupled receptor signaling pathway; retina development in camera-type eye; and sensory perception of taste. Located in photoreceptor outer segment. Part of heterotrimeric G-protein complex. Is active in synapse. Is expressed in several structures, including alimentary system; central nervous system; eye; genitourinary system; and hemolymphoid system gland. Human ortholog(s) of this gene implicated in acute lymphoblastic leukemia; autosomal dominant intellectual developmental disorder 42; congestive heart failure; and myelodysplastic syndrome. Orthologous to human GNB1 (G protein subunit beta 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
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 Gnb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
