What is the function of this protein?
Flippase that catalyzes in an ATP-dependent manner the transport of retinal-phosphatidylethanolamine conjugates like the 11-cis and all-trans isomers of N-retinylidene-phosphatidylethanolamine from the lumen to the cytoplasmic leaflet of photoreceptor outer segment disk membranes, where N-cis-retinylidene-phosphatidylethanolamine (N-cis-R-PE) is then isomerized to its all-trans isomer (N-trans-R-PE) and reduced by RDH8 to produce all-trans-retinol (all-trans-rol) and therefore prevents the accumulation of excess of 11-cis-retinal and its schiff-base conjugate and the formation of toxic bisretinoid (PubMed:10852960, PubMed:10412977, PubMed:22735453).  Displays both ATPase and GTPase activity that is strongly influenced by the lipid environment and the presence of retinoid compounds (By similarity).  Binds the unprotonated form of N-retinylidene-phosphatidylethanolamine with high affinity in the absence of ATP and ATP binding and hydrolysis induce a protein conformational change that causes the dissociation of N-retinylidene-phosphatidylethanolamine (By similarity).
