The transient receptor potential canonical subfamily member 5 (TRPC5), one of seven mammalian TRPC members, is a nonselective calcium-permeant cation channel. TRPC5 is of considerable interest as a drug target in the treatment of progressive kidney disease, depression, and anxiety. Here, we present the 2. Read More

Transient receptor potential canonical (TRPC) 4 and TRPC5 channels are modulated by the Gα-PLC pathway. Since phosphatidylinositol 4,5-bisphosphate (PI(4,5)P) maintains TRPC4 and TRPC5 channel function, the Gα-PLC pathway inhibits channel activity by depleting PI(4,5)P. Here we investigated the difference in PI(4,5)P sensitivity between homomeric and heteromeric TRPC channels. Read More

Aberrant glutathione or Ca(2+) homeostasis due to oxidative stress is associated with the pathogenesis of neurodegenerative disorders. The Ca(2+)-permeable transient receptor potential cation (TRPC) channel is predominantly expressed in the brain, which is sensitive to oxidative stress. However, the role of the TRPC channel in neurodegeneration is not known. Read More

TRPC4 and TRPC5 channels are important regulators of electrical excitability in both gastrointestinal myocytes and neurons. Much is known regarding the assembly and function of these channels including TRPC1 as a homotetramer or a heteromultimer and the roles that their interacting proteins play in controlling these events. Further, they are one of the best-studied targets of G protein-coupled receptors and growth factors in general and Gαq protein coupled receptor or epidermal growth factor in particular. Read More

Members of the Canonical Transient Receptor Potential (TRPC) family of ionic channels are able to form homo- and heterotetrameric channels. Depending on the study, TRPC1 has been detected on both the surface and inside the cell, probably in the endoplasmic reticulum (ER). Likewise, TRPC1 has been described both as a store-operated channel and as one unable to function when forming a homotetramer. Read More
