Summaries for PTAFR Gene

Entrez Gene Summary for PTAFR Gene

  • This gene encodes a seven-transmembrane G-protein-coupled receptor for platelet-activating factor (PAF) that localizes to lipid rafts and/or caveolae in the cell membrane. PAF (1-0-alkyl-2-acetyl-sn-glycero-3-phosphorylcholine) is a phospholipid that plays a significant role in oncogenic transformation, tumor growth, angiogenesis, metastasis, and pro-inflammatory processes. Binding of PAF to the PAF-receptor (PAFR) stimulates numerous signal transduction pathways including phospholipase C, D, A2, mitogen-activated protein kinases (MAPKs), and the phosphatidylinositol-calcium second messenger system. Following PAFR activation, cells become rapidly desensitized and this refractory state is dependent on PAFR phosphorylation, internalization, and down-regulation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]

GeneCards Summary for PTAFR Gene

PTAFR (Platelet-Activating Factor Receptor) is a Protein Coding gene. Diseases associated with PTAFR include melanoma metastasis and lymphoid leukemia. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include G-protein coupled receptor activity and lipopolysaccharide binding. An important paralog of this gene is P2RY2.

UniProtKB/Swiss-Prot for PTAFR Gene

  • Receptor for platelet activating factor, a chemotactic phospholipid mediator that possesses potent inflammatory, smooth-muscle contractile and hypotensive activity. Seems to mediate its action via a G protein that activates a phosphatidylinositol-calcium second messenger system.

Tocris Summary for PTAFR Gene

  • Platelet-activating factor receptor (PAF-R) is a Gq/G11-coupled-protein receptor that has a role in a wide range of biological processes such as vasodilation, superoxide formation, cell proliferation, angiogenesis and regulation of the inflammatory response. PAF-R is linked to multiple intracellular signaling pathways, including the p38 MAPK and PI 3-K pathways, through increasing intracellular calcium mobilization, increasing IP3 synthesis and decreasing cAMP formation. PAF-R has a wide biological distribution with high expression levels in the spleen and skeletal muscles and lower concentrations in the small intestine, lung, heart and liver. The human gene encoding the PAF-R is located on chromosome 1p35-34.3.
