Recombinant Human Histamine H1 receptor (HRH1), Truncated

Uniprot Id

P35367

Target Species

Human

Target Name

HRH1

Target Full Name

Histamine H1 receptor

Target Function

In peripheral tissues, the H1 subclass of histamine receptors mediates the contraction of smooth muscles, increase in capillary permeability due to contraction of terminal venules, and catecholamine release from adrenal medulla, as well as mediating neurotransmission in the central nervous system.

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

G-protein coupled receptor 1 family

Target Synonyms

BPHS, mouse, homolog of; H1 R; H1R; HH1R; HisH1; Histamine H(1) receptor; Histamine H1 receptor; Histamine receptor H1; Histamine receptor subclass H1; Hrh1; HRH1_HUMAN

Target Background

Histamine is a ubiquitous messenger molecule released from mast cells, enterochromaffin-like cells, and neurons. Its various actions are mediated by histamine receptors H1, H2, H3 and H4. The protein encoded by this gene is an integral membrane protein and belongs to the G protein-coupled receptor superfamily. It mediates the contraction of smooth muscles, the increase in capillary permeability due to contraction of terminal venules, the release of catecholamine from adrenal medulla, and neurotransmission in the central nervous system. It has been associated with multiple processes, including memory and learning, circadian rhythm, and thermoregulation. It is also known to contribute to the pathophysiology of allergic diseases such as atopic dermatitis, asthma, anaphylaxis and allergic rhinitis. Multiple alternatively spliced variants, encoding the same protein, have been identified.
