Enzymes

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific 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
Gene Name:
HRH1
Uniprot ID:
P35367
Molecular weight:
55783.6
