Two-pore channels: going with the flows
In recent years, our understanding of the structure, mechanisms and functions of the endo-lysosomal TPC (two-pore channel) family have grown apace. Gated by the second messengers, NAADP and PI(3,5)P(2), TPCs are an integral part of fundamental signal-transduction pathways, but their array and plasti...

Sumario: | In recent years, our understanding of the structure, mechanisms and functions of the endo-lysosomal TPC (two-pore channel) family have grown apace. Gated by the second messengers, NAADP and PI(3,5)P(2), TPCs are an integral part of fundamental signal-transduction pathways, but their array and plasticity of cation conductances (Na(+), Ca(2+), H(+)) allow them to variously signal electrically, osmotically or chemically. Their relative tissue- and organelle-selective distribution, together with agonist-selective ion permeabilities provides a rich palette from which extracellular stimuli can choose. TPCs are emerging as mediators of immunity, cancer, metabolism, viral infectivity and neurodegeneration as this short review attests. |
