Cone photoresponse recovery is accelerated in Rcv-deficient larvae. Time course of b-wave recovery in (a,b) UV spectral ERG, (c) maximum white light ERG and (d) dim white light ERG are shown. Under UV light conditions recoverin2a and combination of recoverin1a and recoverin2a are effective in accelerating the response recovery (a), whereas depleting the effort kinase Grk7a as expected prolongs the recovery time (b). Note that Rcv2a knockdown accelerates response recovery under normal and dim white light conditions, whereas Rcv2b only accelerates recovery under dim light conditions (c,d). Data are presented as mean ± s.e.m.
