'''Crystal structure of the ankyrin repeat domain of human TRPV2'''<br />


==Overview==
==Crystal structure of the ankyrin repeat domain of human TRPV2==
TRPV channels are important polymodal integrators of noxious stimuli, mediating thermosensation and nociception. An ankyrin repeat domain (ARD), which is a common protein-protein recognition domain, is conserved in the, N-terminal intracellular domain of all TRPV channels and predicted to, contain three to four ankyrin repeats. Here we report the first structure, from the TRPV channel subfamily, a 1.7 A resolution crystal structure of, the human TRPV2 ARD. Our crystal structure reveals a six ankyrin repeat, stack with multiple insertions in each repeat generating several unique, features compared with a canonical ARD. The surface typically used for, ligand recognition, the ankyrin groove, contains extended loops with an, exposed hydrophobic patch and a prominent kink resulting from a large, rotational shift of the last two repeats. The TRPV2 ARD provides the first, structural insight into a domain that coordinates nociceptive sensory, transduction and is likely to be a prototype for other TRPV channel ARDs.

== Function ==
[[https://www.uniprot.org/uniprot/TRPV2_HUMAN TRPV2_HUMAN]] Calcium-permeable, non-selective cation channel with an outward rectification. Seems to be regulated, at least in part, by IGF-I, PDGF and 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.<ref>PMID:10201375</ref>

== Publication Abstract from PubMed ==
TRPV channels are important polymodal integrators of noxious stimuli mediating thermosensation and nociception. An ankyrin repeat domain (ARD), which is a common protein-protein recognition domain, is conserved in the N-terminal intracellular domain of all TRPV channels and predicted to contain three to four ankyrin repeats. Here we report the first structure from the TRPV channel subfamily, a 1.7 A resolution crystal structure of the human TRPV2 ARD. Our crystal structure reveals a six ankyrin repeat stack with multiple insertions in each repeat generating several unique features compared with a canonical ARD. The surface typically used for ligand recognition, the ankyrin groove, contains extended loops with an exposed hydrophobic patch and a prominent kink resulting from a large rotational shift of the last two repeats. The TRPV2 ARD provides the first structural insight into a domain that coordinates nociceptive sensory transduction and is likely to be a prototype for other TRPV channel ARDs.
