TRPC Channel Downstream Signaling Cascades
2017The family of TRP channel is comprised of a large group of cation-permeable channels, displaying as signaling integrators for sensing extracellular stimulus and initiating intracellular signaling cascades. This chapter offers a brief review of the signaling molecules related to TRPC channels, the first identified mammalian TRP family.

Inositol lipids and TRPC channel activation
Biochemical Society Symposia, 2007The original hypothesis put forth by Bob Michell in his seminal 1975 review held that inositol lipid breakdown was involved in the activation of plasma membrane calcium channels or ‘gates’. Subsequently, it was demonstrated that while the interposition of inositol lipid breakdown upstream of calcium signalling was correct, it was predominantly the ...

TRPC Channel Structure and Properties
2017TRPC channels are the first identified members in the TRP family. They function as either homo- or heterotetramers regulating intracellular Ca2+ concentration in response to numerous physiological or pathological stimuli. TRPC channels are nonselective cation channels permeable to Ca2+.

The enigmatic TRPCs: multifunctional cation channels
Trends in Cell Biology, 2004Abstract Canonical transient receptor potential (TRPC) channels are vertebrate homologs of the Drosophila photoreceptor channel. Considerable research has been carried out on the seven members of this family, particularly regarding their possible role in Ca 2+ entry.

Trafficking mechanisms and regulation of TRPC channels
Cell Calcium, 2014TRPC channels are Ca(2+)-permeable cation channels which are regulated downstream from receptor-coupled PIP2 hydrolysis. These channels contribute to a wide variety of cellular functions. Loss or gain of channel function has been associated with dysfunction and aberrant physiology.

Physiological Functions and Regulation of TRPC Channels
2014The TRP-canonical (TRPC) subfamily, which consists of seven members (TRPC1-TRPC7), are Ca(2+)-permeable cation channels that are activated in response to receptor-mediated PIP2 hydrolysis via store-dependent and store-independent mechanisms. These channels are involved in a variety of physiological functions in different cell types and tissues.

TRPC Channels in Cardiac Hypertrophy
2013Impaired cardiomyocyte Ca2+ handling is considered as crucial factor programming cardiac hypertrophy and heart failure. It has, however, not been entirely resolved what type of Ca2+ signals is involved in mechanisms inducing hypertrophic remodelling.

TRPC Channels: Integrators of Multiple Cellular Signals
2007TRPC channels are ubiquitously expressed among cell types and mediate signals in response to phospholipase C (PLC)-coupled receptors. TRPC channels function as integrators of multiple signals resulting from receptor-induced PLC activation, which catalyzes the breakdown of phosphatidylinositol 4,5-bisphosphate (PIP2) to produce inositol 1,4,5 ...

Mammalian TRPC channel subunit assembly.
Novartis Foundation symposium, 2004TRPC genes encode a family of ion channel proteins that appear to be responsible for Ca2+ influx following stimulation of membrane receptors linked to phospholipase C. TRPC channels are thought to be tetrameric, and there is growing evidence to suggest heteromultimeric channel assembly.
