General annotation (Comments)

Function

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 inhibit adenylate cyclase activity. Ref.9

Subcellular location

Cell membrane; Multi-pass membrane protein.

Involvement in disease

Periodic fever, menstrual cycle-dependent (PFMC) [MIM:614674]: A condition characterized by recurrent fevers up to 40 degrees Celsius associated with the luteal phase of the menstrual cycle. Women show menstrual cycle-dependent physiologic changes in relation to sex hormone levels. Because ovulation triggers a significant change in the hormonal milieu that is similar to local inflammation, a 0.5 to 1.0 degree Celsius increase in basal body temperature after ovulation is commonly associated with progesterone secretion and is believed to be triggered by the induction of several inflammatory cytokines.
Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.11

Sequence similarities

Belongs to the G-protein coupled receptor 1 family. 5-hydroxytryptamine receptor subfamily. HTR1A sub-subfamily.
