Arrb2 Gene Summary [Rat]
Enables several functions, including 14-3-3 protein binding activity; G protein-coupled receptor binding activity; and arrestin family protein binding activity. Involved in several processes, including regulation of apoptotic process; regulation of protein modification process; and regulation of signal transduction. Located in several cellular components, including basolateral plasma membrane; dendritic spine; and postsynaptic membrane. Is active in glutamatergic synapse and postsynaptic density. Biomarker of several diseases, including alcohol dependence; brain infarction; drug psychosis; liver disease (multiple); and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in glioblastoma; heroin dependence; nicotine dependence; and opiate dependence. Orthologous to human ARRB2 (arrestin beta 2).

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 rat Arrb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
