Hrh4 Gene Summary [Rat]
Enables histamine receptor activity. Predicted to be involved in G protein-coupled receptor signaling pathway, coupled to cyclic nucleotide second messenger; adenylate cyclase-inhibiting G protein-coupled acetylcholine receptor signaling pathway; and chemical synaptic transmission. Predicted to be located in membrane. Predicted to be active in dendrite; plasma membrane; and synapse. Orthologous to human HRH4 (histamine receptor H4).

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 Hrh4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
