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 (By similarity).
Subcellular locations: Cytoplasm, Cytosol, Membrane
Association with membranes is calcium-dependent (By similarity). Enriched in the perinuclear region, probably at the trans Golgi network in response to calcium .
Brain specific.
