Biological functions of TRPs unravelled by spontaneous mutations and transgenic animals

The identification of the biological functions of TRP (transient receptor potential) proteins requires genetic approaches because a selective TRP channel pharmacology to unravel the roles of TRPs is not available so far for most TRPs. A survey is therefore presented of transgenic animal models carrying mutations in TRP genes, as well as of those TRP genes that when mutated result in human disease; the chromosomal locations of TRP channel genes in the human and mouse are also presented.
