5-hydroxytryptamine receptor 7

Gene

Htr7

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

This is one of the several different receptors for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. The activity of this receptor is mediated by G proteins that stimulate adenylate cyclase. This receptor is implicated in the regulation of mammalian circadian rhythms.
