Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Ligands: DGA, F09, K NonStd Res: LHV Related: 5ebl, 5ebm, 5ebw, 5ec2 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum Function [KCSA_STRLI] Acts as a pH-gated potassium ion channel; changing the cytosolic pH from 7 to 4 opens the channel, although it is not clear if this is the physiological stimulus for channel opening. Monovalent cation preference is K(+) > Rb(+) > NH4(+) >> Na(+) > Li(+).
