The Transient Receptor Potential (TRP) superfamily is one of the largest ion channel families and consists of diverse groups of proteins. In mammals, about 28 genes encode the TRP ion channel subunits. The mammalian TRP superfamily comprises six subfamilies known as the TRPC (canonical), TRPV (vanilloid), TRPM (melastatin), TRPML (mucolipins), TRPP (polycystin) and the TRPA (ANKTM1) ion channels1-4.
The TRPC subfamily consists of seven proteins named TRPC1 to 7 which can be further divided into four subgroups based on their sequence homology and functional similarities: TRPC1, TRPC4, TRPC5 TRPC3, TRPC6, TRPC7 and TRPC22,5. They are highly expressed in the central nervous system and to a lesser extent in peripheral tissues.
TRPC6 can form heterotetramers with TRPC3 and TRPC7. It is primarily expressed in brain, lung and muscle. High levels of expression of the channel were also found in human platelets. Recently it was reported that TRPC6 is also expressed in the kidney where a mutated channel has been implicated in kidney failure disease6,7.
Anti-TRPC6 (extracellular) Antibody (#ACC-120) is a highly specific antibody directed against an extracellular epitope of the mouse protein. The antibody can be used in western blot, immunohistochemistry, immunocytochemistry and live cell flow cytometry applications. It has been designed to recognize TRPC6 from rat, mouse and human samples.
