Protein O-GlcNAcase

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

**Definition:** Protein O-GlcNAcase (916 aa, ~103 kDa) is encoded by the human OGA gene. This protein plays a role in the hydrolysis of O-linkages between N-acetylglucosamine (GlcNAc) and serine or threonine protein residues.
