Arrb1 Gene Summary [Rat]
Enables several functions, including AP-2 adaptor complex binding activity; G protein-coupled receptor binding activity; and arrestin family protein binding activity. Involved in several processes, including follicle-stimulating hormone signaling pathway; regulation of ERK1 and ERK2 cascade; and regulation of primary metabolic process. Located in several cellular components, including basolateral plasma membrane; dendritic spine; and postsynaptic membrane. Is active in glutamatergic synapse and postsynaptic density. Used to study congestive heart failure. Biomarker of colitis. Orthologous to human ARRB1 (arrestin beta 1). [provided by Alliance of Genome Resources, Jul 2025]
