HTR5A(5-hydroxytryptamine (serotonin) receptor 5A (5-HT5A、MGC138226、 HTR5A)
//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.
//Subcellular location: Cell membrane; Multi-pass membrane protein.
//Sequence similarities: Belongs to the G-protein coupled receptor 1 family.
SSTR2(somatostatin receptor 2)
//Function: Receptor for somatostatins-14 and -28. This receptor is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase. In addition it stimulates phosphotyrosine phosphatase and PLC via pertussis toxin insensitive as well as sensitive G proteins. In RIN-5F cells, this receptor inhibits calcium entry by suppressing voltage dependent calcium-channels.
//Subcellular location: Cell membrane; Multi-pass membrane protein.
//Tissue specificity: Cerebrum and kidney. In lesser amounts in jejunum, colon and liver.
//Sequence similarities: Belongs to the G-protein coupled receptor 1 family.
RXFP3(relaxin receptor 3) (SALPR、RLN3R1、RXFPR3、 GPCR135、MGC141998、MGC142000、RXFP3)
//Function: Receptor for relaxin-3. Binding of the ligand inhibit cAMP accumulation.
//Subcellular location: Cell membrane; Multi-pass membrane protein.
//Tissue specificity: Expressedpredominantly in brain regions. Highest expression in substantia nigra and pituitary, followed by hippocampus, spinal cord, amygdala, caudate nucleus and corpus callosum, quite low level in cerebellum. In peripheral tissues, relatively high levels in adrenal glands, low levels in pancreas, salivary gland, placenta, mammary gland and testis.
//Sequence similarities: Belongs to the G-protein coupled receptor 1 family.
ADORA3(adenosine A3 receptor) (A3AR、AD026、 bA552M11.5、 RP11-552M11.7、 ADORA3)
//Function: Receptor for adenosine. The activity of this receptor is mediated by G proteins which inhibits adenylyl cyclase. Possible role in reproduction.
//Subcellular location: Cell membrane; Multi-pass membrane protein.
//Sequence similarities: Belongs to the G-protein coupled receptor 1 family.
