TRP channels are a large family (about 28 genes) of plasma membrane, non-selective cationic channels that are either specifically or ubiquitously expressed in excitable and non-excitable cells.1 According to IUPHAR, the TRP family is comprised of three main subfamilies on the basis of sequence homology; TRPC, TRPM and TRPV (to date, three extra subfamilies are considered to belong to the TRP family; the TRPA, TRPML, and TRPP).1-4 The TRPV subfamily consists of six members, TRPV1-6.5
TRPV5 (ECaC) and TRPV6 (CaT1) are unique members of the TRP family. Both are epithelial Ca2+ channels, form constitutively open channels, share high degree of homology (about 66%) with differences in the N- and C-terminus. TRPV6 and TRPV5 are expressed in a 1,25-dihydroxyvitamin D3 dependent manner. In contrast to other members of the TRP family, TRPV5 and TRPV6 are highly Ca2+ selective and are expressed in Ca2+ transporting epithelia where they are assumed to have an important role in Ca2+ reabsorption.6,7 TRPV5 is preferentially expressed in the kidney.
