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

CC -!- ACTIVITY REGULATION: ATPase activity is decreased by cholesterol and
CC ceramide. ATPase activity is stimulated by phosphatidylethanolamine.
CC Phospholipids translocase activity is highly reduced by berylium
CC fluoride and aluminum floride. N-ethylmaleimide inhibits phospholipid
CC translocase activity. {ECO:0000250|UniProtKB:P78363}.
CC -!- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein
CC {ECO:0000255}. Endoplasmic reticulum {ECO:0000250|UniProtKB:P78363}.
CC Cell projection, cilium, photoreceptor outer segment
CC {ECO:0000269|PubMed:9202155}. Note=Localized to the rim and incisures
CC of rod outer segments disks. {ECO:0000269|PubMed:9202155}.
CC -!- TISSUE SPECIFICITY: Retinal-specific (PubMed:9202155). Seems to be
CC exclusively found in the rims of rod photoreceptor cells.
CC {ECO:0000269|PubMed:9202155}.
CC -!- DOMAIN: The second extracellular domain (ECD2, aa 1395-1680) undergoes
CC conformational change in response to its specific interaction with its
CC substrate all-trans-retinal. Nucleotide binding domain 1 (NBD1, aa 854-
CC 1375) binds preferentially and with high affinity with the 11-cis
CC retinal. {ECO:0000250|UniProtKB:P78363}.
CC -!- PTM: N-glycosylated. {ECO:0000250|UniProtKB:F1MWM0}.
CC -!- PTM: Proteolytic cleavage by trypsin leads to a 120-kDa N-terminal
CC fragment and a 115-kDa C-terminal fragment that are linked through
CC disulfide bonds. {ECO:0000250|UniProtKB:F1MWM0}.
CC -!- PTM: Phosphorylation is independent of light exposure and modulates
CC ATPase activity. {ECO:0000250|UniProtKB:F1MWM0}.
CC -!- DISRUPTION PHENOTYPE: Delayed dark adaptation but normal final rod
CC threshold. {ECO:0000269|PubMed:10412977}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. ABCA family.
