Background Information

CALHM2, also named as FAM26B, is a pore-forming subunit of a voltage-gated ion channel. It's a critical ATP-releasing channel that modulates neural activity and as a potential risk factor of depression. There're three isoforms of CALHM2 with calculated MW 36 kDa, 24 kDa and 22 kDa. It's about 32-36 kDa in western blot with membrane protein extraceted lysate.
