背景信息

N-acetylglucosamine-1 (NGLY1), also known as N-glycanase 1. is a cytosolic enzyme critical for the endoplasmic reticulum-associated degradation (ERAD) pathway. It catalyzes the cleavage of N-linked glycans from misfolded glycoproteins during ERAD, enabling proper proteasomal degradation. NGLY1 deficiency, a rare autosomal recessive disorder caused by mutations in the *NGLY1* gene, leads to multisystemic symptoms, including developmental delay, hypotonia, seizures, and liver dysfunction. This condition highlights the enzyme’s essential role in glycoprotein quality control and cellular homeostasis.

Recombinant human NGLY1 protein is produced via heterologous expression systems (e.g., mammalian or insect cells) to ensure proper post-translational modifications and functionality. Its production facilitates research into NGLY1 biology, disease mechanisms, and therapeutic development. Studies using recombinant NGLY1 have explored enzyme replacement therapy (ERT) and gene therapy approaches to address the loss of enzymatic activity in patients. Additionally, it serves as a tool to investigate substrate specificity, interaction partners, and regulatory pathways linked to ERAD and glycoprotein metabolism. Recent efforts also focus on high-throughput screening of small molecules to identify pharmacological chaperones or activators. Recombinant NGLY1’s biochemical characterization has further clarified its catalytic mechanism, including dependence on cytosolic factors like p97/VCP and ubiquitination signals. As a therapeutic candidate, it holds promise for treating NGLY1 deficiency and broader ERAD-related disorders.
