O-GlcNAcase (OGA)

Target
OGA
Molecular classification
Enzyme, Glycoside hydrolase, Hexosaminidase
01

Overview

O-GlcNAcase (OGA) is an enzyme responsible for the removal of O-linked β-N-acetylglucosamine (O-GlcNAc) from serine and threonine residues on proteins. It plays a crucial role in regulating cellular processes, including gene transcription, energy sensing, and stress response. Dysregulation of OGA has been linked to various diseases, including metabolic disorders, neurodegeneration, and cancer. OGA is a therapeutic target and inhibitors like thiamet-G are used to study its function.
