Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Ligands: RB Related: 3f5w, 3f7v, 3f7y, 3fb5, 3fb6, 3fb7 Gene: kcsA, skc1 ("Actinomyces lividans" Krasil'nikov et al. 1965) Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT 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(+). Evolutionary Conservation Check, as determined by ConSurfDB.
