Summary
The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the ABC1 subfamily. Members of the ABC1 subfamily comprise the only major ABC subfamily found exclusively in multicellular eukaryotes. This protein was the first of the ABC transporters to be observed in photoreceptors and may play a role in the photoresponse. Mutations in the human gene are found in patients diagnosed with Stargardt disease and are associated with retinitis pigmentosa-19 and macular degeneration age-related 2.

Comments

Comment Type Description
Disruption Phenotype Delayed dark adaptation but normal final rod threshold. {ECO:0000269|PubMed:10412977}.
Function In the visual cycle, acts as an inward-directed retinoid flipase, retinoid substrates imported by ABCA4 from the extracellular or intradiscal (rod) membrane surfaces to the cytoplasmic membrane surface are all-trans-retinaldehyde (ATR) and N-retinyl-phosphatidyl-ethanolamine (NR-PE). Once transported to the cytoplasmic surface, ATR is reduced to vitamin A by trans- retinol dehydrogenase (tRDH) and then transferred to the retinal pigment epithelium (RPE) where it is converted to 11-cis-retinal. May play a role in photoresponse, removing ATR/NR-PE from the extracellular photoreceptor surfaces during bleach recovery (By similarity). {ECO:0000250}.
Similarity Belongs to the ABC transporter superfamily. ABCA family. {ECO:0000305}.
Similarity Contains 2 ABC transporter domains. {ECO:0000255|PROSITE-ProRule:PRU00434}.
Subcellular Location Membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Note=Localized to outer segment disk edges of rods and cones, with around one million copies/photoreceptor. {ECO:0000250}.
Tissue Specificity Retinal-specific. Seems to be exclusively found in the rims of rod photoreceptor cells.
