Application Abreviews Notes
WB 1/10000 - 1/50000. Detects a band of approximately 130 kDa (predicted molecular weight: 102 kDa).Can be blocked with MGEA5 peptide (ab155521).
IP 1/100 - 1/500.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for Flow Cyt or ICC.
  • 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
      Proteolytically cleaved by caspase-3 during apoptosis. The fragments interact with each other; cleavage does not decrease enzyme activity.
    • Cellular localization
      Cytoplasm and Nucleus.
