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