ZYG11B
Chr 1zyg-11 family member B, cell cycle regulator
Also known as: ZYG11
The ZYG11B protein serves as a substrate adapter in an E3 ubiquitin ligase complex that targets proteins with specific N-terminal sequences for degradation, functioning in protein quality control and clearance of cellular fragments. Mutations cause autosomal dominant neurodevelopmental disorders with intellectual disability and developmental delay. This gene is highly constrained against loss-of-function variants, indicating that proper protein dosage is critical for normal development.
