Description
Product Characteristics: Function: 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.
Subunit: Homotetramer (Probable). Interacts with a cAMP-dependent protein kinase type II regulatory subunit (PRKAR2A or PRKAR2B) and ACBD3. Interacts with RGA.
Subcellular location: Cell membrane, Multi-pass membrane protein. Cytoplasm. Melanosome.
Tissue specificity: Ubiquitously expressed. Expressed in dorsal root ganglia, trigeminal ganglia, spinal chord (Lissauer's tract, dorsal horn and dorsal columns) (at protein level). PTM: N-glycosylated. PTM: Phosphorylated by PKA. SIMILARITY: Belongs to the transient receptor family, TrpV subfamily. SIMILARITY: Contains 3 ANK repeats. Also known as: Transient receptor potential cation channel subfamily V member 2, TrpV2, osm-9-like TRP channel 2, OTRPC2, Vanilloid receptor-like protein 1, VRL-1, Stretch-activated channel 2B, Sac2b, Vrl1, MGC105451.
Target Information: This gene encodes an ion channel that is activated by high temperatures above 52 degrees Celsius. The protein may be involved in transduction of high-temperature heat responses in sensory ganglia. It is thought that in other tissues the channel may be activated by stimuli other than heat.
