Ion Channel-Linked Receptors

Calcium-permeable, non-selective cation channel with an outward rectification. Seems to be regulated, at least in part, by growth factors, like IGF1, PDGF and morphogenetic neuropeptide head activator. May transduce physical stimuli in mast cells. Activated by temperatures higher than 52 degrees Celsius; is not activated by vanilloids and acidic pH. TRPV2 Protein, Rat, Recombinant (His) is expressed in E. coli expression system with N-10xHis tag. The predicted molecular weight is 88.2 kDa and the accession number is Q9WUD2.

TRPA1 Protein, Rat, Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 27.3 kDa and the accession number is Q6RI86.

Cholinergic nicotinic receptor (CHRN) gene family has been known to mediate the highly additive effects of nicotine in the body, and implicated nicotine dependence (ND) and related phenotypes. Cigarette smoking is protective in Parkinson's disease (PD), possibly because of nicotine action on brain nicotinic-acetylcholine receptors. The beta3 nicotinic-acetylcholine receptor subunit (encoded by CHRNB3) is depleted in the striatum of PD patients and associated with nicotine dependence. CHRNB3 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with hFc tag. The predicted molecular weight is 51 kDa and the accession number is Q05901.

Genetic variation in the cluster on chromosome 15, encoding the nicotinic acetylcholine receptor subunits (CHRNA5-CHRNA3-CHRNB4), has shown strong associations with tobacco consumption and an additional risk increase in smoking-related diseases such as chronic obstructive pulmonary disease (COPD), peripheral artery disease and lung cancer. CHRNA5 may influence susceptibility to lung cancer among Han smokers. Genetic variation in nicotinic receptor alpha 5 (CHRNA5) has been associated with increased risk of addiction-associated phenotypes in humans.

Thought to form a receptor-activated non-selective calcium permeant cation channel. Probably is operated by a phosphatidylinositol second messenger system activated by receptor tyrosine kinases or G-protein coupled receptors. Seems to be also activated by intracellular calcium store depletion. TRPC1 Protein, Mouse, Recombinant (His) is expressed in E. coli expression system with N-10xHis tag. The predicted molecular weight is 94.0 kDa and the accession number is Q61056.
