  • General notes
    Expression in primary culture of RPE cells is undetectable in Western blot after day 14. Established cell lines are similarly devoid of RPE65 protein, as indicated in western blot. However, mRNA levels are detectable by Northern for at least 7 weeks. (see reference Hamel, C.P., et al. Molecular Cloning and expression of RPE65 a novel retinal pigment epithelium-specific microsomal protein that is post-transcriptionally regulated in vitro. JBC. 268(21): 15751-15757, 1993.)

    Abcam is committed to meeting high standards of ethical manufacturing and has decided to discontinue this product by June 2019 as it has been generated by the ascites method. We are sorry for any inconvenience this may cause.

  • Function
    Plays important roles in the production of 11-cis retinal and in visual pigment regeneration. The soluble form binds vitamin A (all-trans-retinol), making it available for LRAT processing to all-trans-retinyl ester. The membrane form, palmitoylated by LRAT, binds all-trans-retinyl esters, making them available for IMH (isomerohydrolase) processing to all-cis-retinol. The soluble form is regenerated by transferring its palmitoyl groups onto 11-cis-retinol, a reaction catalyzed by LRAT. The enzymatic activity is linearly dependent of the expression levels and membrane association.
  • Tissue specificity
    Retinal pigment epithelium specific.
  • Involvement in disease
    Defects in RPE65 are the cause of Leber congenital amaurosis type 2 (LCA2) [MIM:204100]. LCA designates a clinically and genetically heterogeneous group of childhood retinal degenerations, generally inherited in an autosomal recessive manner. Affected infants have little or no retinal photoreceptor function as tested by electroretinography. LCA represents the most common genetic cause of congenital visual impairment in infants and children.
    Defects in RPE65 are the cause of retinitis pigmentosa type 20 (RP20) [MIM:613794]. RP leads to degeneration of retinal photoreceptor cells. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. RP20 inheritance is autosomal dominant.
  • Sequence similarities
    Belongs to the carotenoid oxygenase family.
  • Post-translational
    Palmitoylation by LRAT regulates ligand binding specificity; the palmitoylated form (membrane form) specifically binds all-trans-retinyl-palmitate, while the soluble unpalmitoylated form binds all-trans-retinol (vitamin A).
  • Cellular localization
    Cytoplasm. Cell membrane. Attached to the membrane by a lipid anchor when palmitoylated (membrane form), soluble when unpalmitoylated.

  • ARPE19 (spontaneously arising human retinal pigment epithelia cell line) cells stained for RPE65 (green) using ab13826 (1/100 dilution) in ICC/IF.

    Cells were fixed in 4% PFA for 10 minutes, permeabilized in PBS containing 0.2% Triton X-100 (PBS-T) for 10 minutes, then blocked for 1 hour in 10% normal goat serum containing 1% BSA in PBS-T. Incubated with primary antibody at 4°C.
