Nus1 Protein Nogo B Receptor plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
NUS1 (Nogo-B Receptor, also known as NgBR) is an essential protein encoded by the [NUS1 gene](genes/NUS1) on chromosome 6p22.1. It functions as a receptor for Nogo-B (RTN4B), a member of the reticulon family, and plays critical roles in dolichol biosynthesis, protein N-glycosylation, and mitochondrial function. NUS1 has emerged as a significant player in neurodegenerative diseases, particularly [Parkinson's disease](/diseases/parkinsons-disease), where mutations have been linked to autosomal dominant PD. Additionally, NUS1 mutations cause a rare congenital disorder of glycosylation (NUS1-CDG). [@nus2019]
