Store-operated calcium channels.
Store-operated calcium channels (SOCs) are a major pathway for calcium signaling in virtually all metozoan cells and serve a wide variety of functions ranging from gene expression, motility, and secretion to tissue and organ development and the immune response. SOCs are activated by the depletion of Ca(2+) from the endoplasmic reticulum (ER), triggered physiologically through stimulation of a d...
متن کاملStore-operated calcium channels.
In electrically nonexcitable cells, Ca(2+) influx is essential for regulating a host of kinetically distinct processes involving exocytosis, enzyme control, gene regulation, cell growth and proliferation, and apoptosis. The major Ca(2+) entry pathway in these cells is the store-operated one, in which the emptying of intracellular Ca(2+) stores activates Ca(2+) influx (store-operated Ca(2+) entr...
متن کاملSTIM1 Protein Activates Store-Operated Calcium Channels in Cellular Model of Huntington’s Disease
We have shown that the expression of full-length mutated huntingtin in human neuroblastoma cells (SK-N-SH) leads to an abnormal increase in calcium entry through store-operated channels. In this paper, the expression of the N-terminal fragment of mutated huntingtin (Htt138Q-1exon) is shown to be enough to provide an actual model for Huntington's disease. We have shown that Htt138Q-1exon express...
متن کاملSTIM1 has a plasma membrane role in the activation of store-operated Ca(2+) channels.
Receptor-induced Ca(2+) signals are key to the function of all cells and involve release of Ca(2+) from endoplasmic reticulum (ER) stores, triggering Ca(2+) entry through plasma membrane (PM) "store-operated channels" (SOCs). The identity of SOCs and their coupling to store depletion remain molecular and mechanistic mysteries. The single transmembrane-spanning Ca(2+)-binding protein, STIM1, is ...
متن کاملTRPC channels as effectors of cardiac hypertrophy.
Transient receptor potential (TRP) channels of multiple subclasses are expressed in the heart, although their functions are only now beginning to emerge, especially for the TRPC subclass that appears to regulate the cardiac hypertrophic response. Although TRP channels permeate many different cations, they are most often ascribed a specific biological function because of Ca(2+) influx, either fo...
