UBR5 (Ubiquitin Protein Ligase E3 Component N-Recognin 5): UBR5 is a gene that encodes an E3 ubiquitin ligase involved in protein degradation through the ubiquitin-proteasome pathway. It plays a key role in regulating protein stability and turnover. Dysfunctions in UBR5 can affect various cellular processes and are linked to cancer development and neurodegenerative diseases. Understanding UBR5 is important for studying protein homeostasis and cellular quality control.
