Drd5 Gene Summary [Rat]
Enables G-protein alpha-subunit binding activity and dopamine neurotransmitter receptor activity. Involved in several processes, including adenylate cyclase-activating dopamine receptor signaling pathway; negative regulation of protein kinase activity; and visual learning. Acts upstream of or within adenylate cyclase-activating G protein-coupled receptor signaling pathway. Located in several cellular components, including brush border membrane; dendritic spine; and neuronal cell body. Is active in glutamatergic synapse and postsynaptic density membrane. Human ortholog(s) of this gene implicated in attention deficit hyperactivity disorder and blepharospasm. Orthologous to human DRD5 (dopamine receptor D5).

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 Drd5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
