Calcium-binding protein that may play a role in the regulation of voltage-dependent calcium channels. May also play a role in cyclic-nucleotide-mediated signaling through the regulation of adenylate and guanylate cyclases. Oligomer; oligomerization is calcium-dependent. May interact with the voltage-dependent P/Q- and N-type calcium channels CACNA1A and CACNA1B. Association with membranes is calcium-dependent (By similarity). Enriched in the perinuclear region, probably at the trans Golgi network in response to calcium (By similarity). Binds 3 calcium via EF-hand domains. The cryptic EF-hand 1 does not bind calcium. Myristoylation facilitates association with membranes. Belongs to the recoverin family.
