CC -!- FUNCTION: Regulatory subunit of the calcium activated potassium KCNMA1
CC (maxiK) channel. Modulates the calcium sensitivity and gating kinetics
CC of KCNMA1, thereby contributing to KCNMA1 channel diversity.
CC {ECO:0000256|RuleBase:RU368097}.
CC -!- SUBUNIT: Interacts with KCNMA1 tetramer. There are probably 4 molecules
CC of KCMNB per KCNMA1 tetramer. {ECO:0000256|RuleBase:RU368097}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141,
CC ECO:0000256|RuleBase:RU368097}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141, ECO:0000256|RuleBase:RU368097}.
CC -!- PTM: N-glycosylated. {ECO:0000256|RuleBase:RU368097}.
CC -!- SIMILARITY: Belongs to the KCNMB (TC 8.A.14.1) family.
CC {ECO:0000256|RuleBase:RU368097}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|RuleBase:RU368097}.
