Gnb5 Gene Summary [Mouse]

Predicted to enable several functions, including G-protein gamma-subunit binding activity; GTPase activating protein binding activity; and protein-folding chaperone binding activity. Predicted to contribute to GTPase activator activity. Acts upstream of or within G protein-coupled receptor signaling pathway; dark adaptation; and light adaption. Located in nucleus and plasma membrane. Is active in several cellular components, including dendrite; parallel fiber to Purkinje cell synapse; and synaptic membrane. Is expressed in several structures, including brain; eye; genitourinary system; liver; and lung. Human ortholog(s) of this gene implicated in intellectual developmental disorder with cardiac arrhythmia. Orthologous to human GNB5 (G protein subunit beta 5).

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 Gnb5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
