Recoverin (UniProt P35243; also known as Cancer-associated retinopathy antigen, Cancer-associated retinopathy protein, Protein CAR) is encoded by the RCVRN (also known as RCV1) gene (Gene ID 5957) in human. The photoreceptor protein recoverin is a member of the EF-hand neuronal calcium sensor (NCS) proteins. Recoverin is initially produced as a 200-amino acid protein whose N-terminal initiator methionine is removed posttranslationally. Recoverin is composed of four EF-hand domains (a.a. 25-60, 61-96, 97-132, 147-182), with the second and third EF-hand regions mediating low- and high-affinity calcium binding, respectively. In photoreceptor cells, recoverin functions as a Ca2+-dependent inhibitor of G-protein-coupled receptor kinase 1 (GRK1). Recoverin plays an important role in mediating calcium-dependent rod and cone light adaptation. Recoverin delays the rod & cone response under dim light when [Ca2+] is high by inhibiting GRK1-catalyzed visual pigment phosphorylation, but has little effect during light adaptation when [Ca2+]i is lowered.
