Calcium-binding protein that may play a role in the regulation of voltage-dependent calcium channels (By similarity). May also play a role in cyclic-nucleotide-mediated signaling through the regulation of adenylate and guanylate cyclases (PubMed:15336960). 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 (PubMed:8360179, PubMed:1543495). Enriched in the perinuclear region, probably at the trans Golgi network in response to calcium (By similarity). Neuron-specific in the hippocampus (PubMed:1280427). Also detected in olfactory eptihelium (PubMed:15336960). 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.
