General description

The β-N-acetylglucosaminidase (OGA) gene encodes two alternatively spliced isoforms that are widely expressed in mammalian tissues. OGA (also known as O-GlcNAcase, MGEA5, NCOAT) belongs to the family of 84 glycoside hydrolases. The longer OGA form is a bifunctional nuclear/cytoplasmic enzyme that contains two distinct domains, an O-GlcNAcase domain at the N-terminus and a C-terminal putative histone acetyltransferase (HAT) domain. The shorter OGA form contains only the N-terminal O-GlcNAcase domain.

Immunogen

synthetic peptide corresponding to a sequence near the C-terminus of human O-GlcNAcase (OGA), conjugated to KLH. The corresponding sequence is identical in human OGA isoform B, and highly conserved (single amino acid substitution) in rat and mouse OGA.

Application

Anti-O-GlcNAcase (OGA) (C-terminal region) antibody produced in rabbit has been used in:
  • Western blotting
  • Immunoprecipitation
  • Microarray analysis

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions

β-N-acetylglucosaminidase (OGA) along with O-GlcNAc transferase (OGT) are key enzymes which regulate cycling O-linked N-acetylglucosamine. OGA is responsible for cleaving the modification from target proteins. OGA is also glycosylated by OGT and a regulatory feedback loop exists between these two enzymes. OGA and OGT have been found to strongly associate together in transcriptional co-repression complexes with histone deacetylases (HDACs).

Physical form

Protein O-GlcNAcylation is a nutrient and stress-sensitive protein post-translational modification (PTM). The addition of an O-GlcNAc molecule to proteins is catalyzed by O-GlcNAc transferase (OGT), whereas O-GlcNAcase (OGA) enzyme is responsible for removal of this PTM. Previous work showed that
