WebApr 26, 2024 · Two-pore channels (TPCs) are ligand-gated cation-selective ion channels that are preserved in plant and animal cells. In the latter, TPCs are located in membranes of acidic organelles, such as endosomes, lysosomes, and endolysosomes. Here, we focus on the function of these unique ion channels in mast cells, which are leukocytes that mature … WebTASK-3 is a dual-hole K+ selective channel that provides background potassium conductance.The human KCNK9 gene encodes the pore-forming subunit of TASK-3.The TASK-3 channel expressed in the CNS can stabilize the resting membrane potential and is a therapeutic target for inhaled anesthetics as a channel opener.
