Retinal-Specific Phospholipid-Transporting ATPase ABCA4

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** Retinal-specific phospholipid-transporting ATPase ABCA4 (2273 aa, ~256 kDa) is encoded by the human ABCA4 gene. This protein is involved in ATP-dependent transport of retinal-phosphatidylethanolamine conjugates from the lumen to the cytoplasmic leaflet of photoreceptor outer segment disk membranes.
