Also known as: 5-HT2C; 5HT-1C; 5-HTR2C
Summary: Serotonin (5-hydroxytryptamine, 5-HT), a neurotransmitter, elicits a wide array of physiological effects by binding to several receptor subtypes, including the 5-HT2 family of seven-transmembrane-spanning, G-protein-coupled receptors, which activate phospholipase C and D signaling pathways. This gene encodes the 2C subtype of serotonin receptor and its mRNA is subject to multiple RNA editing events, where genomically encoded adenosine residues are converted to inosines. RNA editing is predicted to alter amino acids within the second intracellular loop of the 5-HT2C receptor and generate receptor isoforms that differ in their ability to interact with G proteins and the activation of phospholipase C and D signaling cascades, thus modulating serotonergic neurotransmission in the central nervous system. Studies in rodents show altered patterns of RNA editing in response to drug treatments and stressful situations. [provided by RefSeq, Jul 2008]

Our results demonstrate subregion- and layer-specific expression of the 5-HT2AR and 5-HT2CR proteins using immunofluorescence and single recognition PLA, and a spatially close (within 40 nm) interaction between the 5-HT2AR and 5-HT2CR that occurs along a dorsal-ventral gradient in the rat medial prefrontal cortex.

This study found that behavioral stimulation of tongue use is associated with an increased 5-HT2C receptor immunostaining in the XII nucleus and an increased c-Fos expression in a subset of 5-HT neurons located in the medullary raphe region most relevant for serotonergic control of XII motoneurons.
Title: Increased tongue use enhances 5-HT(2C) receptor immunostaining in hypoglossal motor nucleus.
Injection of a highly selective 5-HT2C receptor agonist, AR231630, into the ventral tegmental area (VTA) is sufficient to inhibit the expression of amphetamine-induced and basal locomotor activity as well as food intake in rats. Blockade of the anorexic effect of peripheral AR231630 on feeding by intra-VTA 5-HT2C receptor antagonist SB24208 injections suggests the involvement of 5-HT2C receptors in these effects.
Title: 5-HT(2C) receptors in the ventral tegmental area, but not in the arcuate nucleus, mediate the hypophagic and hypolocomotor effects of the selective 5-HT(2C) receptor agonist AR231630 in rats.
This study demonstrated that the proportion of 5-HT2C-R-expressing striatal neurons was 23% (dorsolateral caudate-putamen), 37% (ventromedial caudate-putamen), 53% (nucleus accumbens-core), and 49% (nucleus accumbens-shell).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
