Background

Cytosolic Ca2+ serves as an intracellular mediator for many extracellular signals. At rest, cells maintain a low Ca2+ concentration of ~ 10-7 M. Upon activation of the phospholipase C-dependent mechanism, the cytosolic Ca2+ concentration rises. In many vertebrate and invertebrate cells, the influx of Ca2+ is biphasic. Mobilization of Ca2+ from internal stores (sarcoplasmic reticulum in muscle cells and endoplasmic reticulum in other cell types) drives the initial burst. The second phase, referred to as capacitative Ca2+ entry (CCE) or store-operated Ca2+ entry, occurs when the depletion of intracellular Ca2+ stores activates a non-voltagesensitive plasma membrane Ca2+ conductance.1 The channels responsible for this conductance have been referred to as SOCs for store-operated channels. A Drosophila gene, trp (transient receptor potential), encodes the first identified candidate for such a channel. In recent years, seven mammalian TRP channels, named TRPC1-TRPC7, have been cloned. TRP channels (TRPCs) are ubiquitous, yet are most abundant in muscles and nerves. They differ in their method of activation and in their channel conductance.2 All TRPCs have six transmembrane segments with a pore-forming loop between the fifth and sixth segment. This structure is similar to the pore-forming subunits of other channels including voltage-gated Na+, K+ and Ca2+ channels and cyclic nucleotide gated channels. The TRP isoforms can be divided into three subfamilies based on characteristic sequence domains. The long TRP channels (LTRPCs) have four related sequences with open reading frames (ORFs) coding for approximately 1600 amino acids. The other two subfamilies are characterized by shorter ORFs, coding for about 900 amino acids. These are called the short TRP (STRP) and osm-9-like (OTRP) channel families. The OTRPCs are named after the first member of this family to be identified, the C. elegans clone osm-9.2 The sub-families differ in other ways. STRPCs have two to four ankyrin domains in their N-terminal cytosolic tail, where as OTRPCs have three or more and LTRPCs have none. Furthermore, a proline-rich motif in the cytosolic C-terminal region near the sixth transmembrane segment can be found in STRPCs and LTRPCs, but not in OTRPCs.2 The sub-families also differ in their functional properties. The seven mammalian TRPCs (TRPCs 1-7) are all members of the STRPC sub-family. STRPCs are activated in response to phospholipase C activation. OTRPCs appear to be activated by physical or chemical stimuli such as heat, osmotic stress or mechanical stress. The function and activation of LTRPCs is not yet known since their ability to function as channels has not been demonstrated. TRPC4 has been identified in adrenal gland, testis and brain.2 Full-length cDNAs have been cloned from bovine, human, mouse and rat species. TRPC4 is a non-selective cation channel that integrates signaling pathways from G-protein-coupled receptors and receptor tyrosine kinases independently of the depletion of calcium stores.3
