Purified Membrane Proteins

Calcium homeostasis modulator protein 3 (Protein A)

Pore-forming subunit of a voltage-gated ion channel, also permeable to larger molecules including ATP. Together with CALHM1, forms a fast-activating voltage-gated ATP-release channel in type II taste bud cells (TBCs). CALHM1-CALHM3-mediated ATP released acts as a neurotransmitter to gustatory neurons in response to GPCR-mediated tastes, including sweet, bitter and umami substances. {ECO:0000250|UniProtKB:J3QMI4}.
