Two pore channel
WebJan 18, 2016 · Two-pore channels (TPCs) constitute a family of intracellular cation channels with diverse permeation properties and functions in animals and plants. In the model plant Arabidopsis, the vacuolar cation channel TPC1 is involved in propagation of calcium waves and in cation homeostasis. Here, we discovered that the dimerization of a predicted helix … WebSolid lines show channel closed and open levels, while dashed lines indicate thresholds 1, 2, and 3 at 10, 50, and 85% of the open level.

WebJun 19, 2007 · So far only one, the slow vacuolar (SV), channel has been identified at the gene level and found to be encoded by the TPC1 (two-pore channel) gene ().The SV channel is ubiquitous in plants and is believed to play a role in cation homeostasis and Ca 2+ signaling. It forms the predominant tonoplast conductance and was one of the first plant … WebJul 20, 2009 · The two-pore channel (TPC) has recently emerged as a novel intracellular calcium release channel in plants (Peiter et al., 2005). TPCs have a domain structure similar to one-half of voltage-sensitive Ca 2+ channels; i.e., they are composed of two repeats of six trans-membrane helices each encompassing a putative pore (Peiter et al., 2005).
WebMuch excitement surrounded the proposal that a family of endo-lysosomal channels, the two-pore channels (TPCs) were the long sought after targets of the Ca(2+) -mobilising messenger, nicotinic acid adenine dinucleotide phosphate (NAADP).
