Comment typeDescription
DiseasePeriodic 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. {ECO:0000269|PubMed:21990073}. Note=The disease is caused by mutations affecting the gene represented in this entry.
FunctionG-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. {ECO:0000269|PubMed:22957663, ECO:0000269|PubMed:3138543, ECO:0000269|PubMed:8138923, ECO:0000269|PubMed:8393041}.
