Hrh2 Gene Summary [Mouse]
Predicted to enable heterocyclic compound binding activity; histamine receptor activity; and neurotransmitter receptor activity. Acts upstream of or within several processes, including epithelial cell morphogenesis; gastric acid secretion; and learning or memory. Predicted to be active in dendrite and plasma membrane. Is expressed in brain; early conceptus; stomach; and uterus. Orthologous to human HRH2 (histamine receptor H2). [provided by Alliance of Genome Resources, Apr 2025]

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 Hrh2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- G-protein coupled receptor
- histamine receptor
- Cholecystokinin A receptor, N-terminal
- binding protein
- 7 transmembrane receptor (rhodopsin family)
