CC -!- FUNCTION: Regulatory subunit of calcineurin, a calcium-dependent,
CC calmodulin stimulated protein phosphatase. Confers calcium sensitivity.
CC Plays a central role in virulence and antifungal drug action.
CC {ECO:0000269|PubMed:11251806}.
CC -!- SUBUNIT: Composed of a catalytic subunit (A) and a regulatory subunit
CC (B). {ECO:0000250}.
CC -!- MISCELLANEOUS: This protein has four functional calcium-binding sites.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the calcineurin regulatory subunit family.
CC {ECO:0000305}.
