Protein Domain : Two pore channel protein 2 IPR028798

Type	Family
Description	This entry represents TPC2. It modulates neural differentiation of mouse embryonic stem cells [ ]. It may also be involved in smooth muscle contraction []. Two-pore segment channels (TPCs or TPCNs) are located in membranes of acidic intracellular organelles (such as endo-lysosomes and plant vacuoles) and contain two putative pore-forming repeats. Each of these repeats contains six transmembrane segments and an intervening pore-loop, an architecture featured in voltage-gated channels [ ]. Functional TPC channels are assembled from two TPC protein subunits forming a pore that conducts mainly Ca2 and Na. TPCs exist as three isoforms (TPC1-3): TPC1 and TPC2 are the most universal isoforms since TPC3 is absent from the genomes of many animals including those of human, mice, rats and flies [].
Short Name	TPC2
