5-hydroxytryptamine receptor 1A

From NCBI Gene:

This gene encodes a G protein-coupled receptor for 5-hydroxytryptamine (serotonin), and belongs to the 5-hydroxytryptamine receptor subfamily. Serotonin has been implicated in a number of physiologic processes and pathologic conditions. Inactivation of this gene in mice results in behavior consistent with an increased anxiety and stress response. Mutation in the promoter of this gene has been associated with menstrual cycle-dependent periodic fevers. [provided by RefSeq, Jun 2012]

From UniProt:

G-protein coupled receptor for 5-hydroxytryptamine (serotonin). Also functions as a receptor for various drugs and psychoactive substances. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Beta-arrestin family members inhibit signaling via G proteins and mediate activation of alternative signaling pathways. Signaling inhibits adenylate cyclase activity and activates a phosphatidylinositol-calcium second messenger system that regulates the release of Ca(2+) ions from intracellular stores. Plays a role in the regulation of 5-hydroxytryptamine release and in the regulation of dopamine and 5-hydroxytryptamine metabolism. Plays a role in the regulation of dopamine and 5-hydroxytryptamine levels in the brain, and thereby affects neural activity, mood and behavior. Plays a role in the response to anxiogenic stimuli.

  • Periodic fever, menstrual cycle-dependent

From UniProt:

Periodic fever, menstrual cycle-dependent (PFMC): 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.
