RL Submitted (AUG-2006) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Calcium-binding protein that may play a role in the
CC regulation of voltage-dependent calcium channels. May also play a role
CC in cyclic-nucleotide-mediated signaling through the regulation of
CC adenylate and guanylate cyclases. {ECO:0000250|UniProtKB:P84074,
CC ECO:0000250|UniProtKB:P84076}.
CC -!- SUBUNIT: Oligomer; oligomerization is calcium-dependent. May interact
CC with the voltage-dependent P/Q- and N-type calcium channels CACNA1A and
CC CACNA1B. {ECO:0000250|UniProtKB:P84074}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000250|UniProtKB:P84074,
CC ECO:0000250|UniProtKB:P84076}. Membrane {ECO:0000250|UniProtKB:P84076};
CC Peripheral membrane protein {ECO:0000250|UniProtKB:P84076}.
CC Note=Association with membranes is calcium-dependent (By similarity).
CC Enriched in the perinuclear region, probably at the trans Golgi network
CC in response to calcium (By similarity). {ECO:0000250|UniProtKB:P84074,
CC ECO:0000250|UniProtKB:P84076}.
CC -!- DOMAIN: Binds 3 calcium via EF-hand domains. The cryptic EF-hand 1 does
CC not bind calcium. {ECO:0000250|UniProtKB:P84074}.
CC -!- PTM: Myristoylation facilitates association with membranes.
CC {ECO:0000250|UniProtKB:P84076}.
CC -!- SIMILARITY: Belongs to the recoverin family. {ECO:0000305}.
