  Transient receptor potential
Drosophila transient receptor potential (Trp) serves dual roles as an essential cation channel during response to light and as a molecular anchor for the PDZ protein, INAD (inactivation no afterpotential D).
The transient receptor potential (Trp) superfamily is comprised of a large group of related cation channels that function in sensory processes ranging from phototransduction to touch, hearing, taste, olfaction, osmosensation, and thermosensation (Montell, 2005b).
Drosophila Trp is a multifunctional protein because it serves both as a cation channel and a molecular anchor required for the retention of the scaffold protein, INAD, in the rhabdomeres.

  Transient receptor potential - Wikipedia, the free encyclopedia
The phrase Transient receptor potential or TRP is appended to at least three classes of ion channels which mediate the response of a cell to external stimuli (electrical charge, substances, and forces) by increasing or decreasing its selective permeability to particular ions.
The effect of this change is to modify the potential difference between inside and outside of the cell.
Transient receptor potential ion channels are named after the role of the channels in Drosophila phototransduction.

Transient receptor potential (Trp) and related proteins are thought to be Ca2+ ion channel subunits that mediate capacitative Ca2+ entry in response to a range of external and internal cell stimuli.
Studies on the visual transduction system in Drosophila led to the molecular cloning of Trp and the cDNA of a related protein, Trp-like, which show similarity to voltage gated Ca2+ channels in the regions known as S3 through S6, including the S5-S6 linker that forms the ion-selective channel pore [2].
The Trp family is thought to encode at least 20 Ca2+-permeable channel proteins.

In addition, mutations in TRP channels are known to be the basis for a number of inherited diseases, including mucolipidosis and polycystic kidney disease.
However, there is a great deal of controversy regarding the mechanisms of activation and regulation of many TRPs, especially those thought to be involved in the long elusive mechanism of store-operated channels.
Additionally, the roles of TRPs in diseases will be addressed, including the potential for treating diseases through knowledge of their regulation, and through design of therapeutic agents to modify their behavior.
