DESCRIPTION

Also known as RECO_MOUSE, Rcvrn, Rcv1. Acts as a calcium sensor and regulates phototransduction of cone and rod photoreceptor cells (By similarity). Modulates light sensitivity of cone photoreceptor in dark and dim conditions (PubMed:25673692). In response to high Ca(2+) levels induced by low light levels, prolongs RHO/rhodopsin activation in rod photoreceptor cells by binding to and inhibiting GRK1-mediated phosphorylation of RHO/rhodopsin (By similarity). Plays a role in scotopic vision/enhances vision in dim light by enhancing signal transfer between rod photoreceptors and rod bipolar cells (PubMed:15882641). Improves rod photoreceptor sensitivity in dim light and mediates response of rod photoreceptors to facilitate detection of change and motion in bright light (PubMed:29435986). Homodimer; disulfide-linked (By similarity). Homodimerization is caused by prolonged intense illumination (By similarity). May form a complex composed of RHO, GRK1 and RCVRN in a Ca(2+)-dependent manner; RCVRN prevents the interaction between GRK1 and RHO (By similarity). Interacts (via C-terminus) with GRK1 (via N-terminus); the interaction is Ca(2+)-dependent (By similarity).
