Anti-CALHM1 antibody,Abcam,AB106561

Target data Pore-forming subunit of gustatory voltage-gated ion channels required for sensory perception of sweet, bitter and umami tastes (By similarity). With CALHM3 forms a fast-activating voltage-gated ATP-release channel in type II taste bud cells, ATP acting as a neurotransmitter to activate afferent neural gustatory pathways (By similarity) (PubMed : 23467090). Acts both as a voltage-gated and calcium-activated ion channel : mediates neuronal excitability in response to membrane depolarization and low extracellular Ca(2+) concentration (PubMed : 22711817, PubMed : 23300080). Has poor ion selectivity and forms a wide pore (around 14 Angstroms) that mediates permeation of small ions including Ca(2+), Na(+), K(+) and Cl(-), as well as larger ions such as ATP(4-) (PubMed : 22711817, PubMed : 23300080, PubMed : 32832629, PubMed : 37380652). Mediates Ca(2+) influx and downstream activation of the ERK1 and ERK2 cascade in neurons (PubMed : 23345406). Triggers endoplasmic reticulum stress by reducing the Ca(2+) content of the endoplasmic reticulum (PubMed : 21574960). May indirectly control amyloid precursor protein (APP) proteolysis and aggregated amyloid-beta (Abeta) peptides levels in a Ca(2+)-dependent manner (PubMed : 18585350).
