Target

  • Function

    Isoform 1: Cleaves GlcNAc but not GalNAc from O-glycosylated proteins. Can use p-nitrophenyl-beta-GlcNAc and 4-methylumbelliferone-GlcNAc as substrates but not p-nitrophenyl-beta-GalNAc or p-nitrophenyl-alpha-GlcNAc (in vitro) (PubMed:11148210). Does not bind acetyl-CoA and does not have histone acetyltransferase activity (PubMed:24088714).
    Isoform 3: Cleaves GlcNAc but not GalNAc from O-glycosylated proteins. Can use p-nitrophenyl-beta-GlcNAc as substrate but not p-nitrophenyl-beta-GalNAc or p-nitrophenyl-alpha-GlcNAc (in vitro), but has about six times lower specific activity than isoform 1.
  • Tissue specificity

    Ubiquitous. Shows highest expression in the brain, placenta and pancreas.
  • Sequence similarities

    Belongs to the glycosyl hydrolase 84 family.
  • Post-translational
    modifications

    Proteolytically cleaved by caspase-3 during apoptosis. The fragments interact with each other; cleavage does not decrease enzyme activity.
  • Cellular localization

    Cytoplasm and Nucleus.

    Question

    abcam,

    Hello, abcam.

    I ordered a antibody(ab124807) from your company recently, and I got it several weeks ago.

    I have a question about the product.

    I tested it by western blotting, and it shows several bands.

    So I want to check whether those are specific or not.

    Because it is known that m/w of OGA's splice variant form is almost 70 kDa, and that of caspase-cleaved OGA is around 65 kDa.

    I want to know the exact epitope(peptide region) of this ab.(ab124807).

    See the attached files, please.

    Thank you.
