背景信息

Ubiquitin-conjugating enzyme 11 (UBC11), also known as UBE2C or UBCH10. is a member of the E2 ubiquitin-conjugating enzyme family critical for the ubiquitin-proteasome system (UPS), which regulates protein degradation and cellular homeostasis. Functioning as a key mediator in the ubiquitination cascade, UBC11 transfers ubiquitin from E1-activating enzymes to substrate proteins, often in collaboration with E3 ubiquitin ligases. This post-translational modification typically marks target proteins for proteasomal degradation, influencing processes like cell cycle progression, DNA repair, and apoptosis.

Structurally, UBC11 contains a conserved catalytic core domain responsible for binding ubiquitin and E3 ligases. Its activity is particularly notable during the mitotic phase of the cell cycle, where it participates in the degradation of anaphase-promoting complex/cyclosome (APC/C) substrates, ensuring proper chromosome segregation and mitotic exit. Dysregulation of UBC11 has been linked to genomic instability and oncogenesis, with overexpression observed in various cancers, correlating with poor prognosis and therapeutic resistance.

Recombinant UBC11 is engineered for biochemical and functional studies, often expressed in bacterial or mammalian systems to preserve post-translational modifications. Purified recombinant UBC11 enables in vitro ubiquitination assays, structural analyses (e.g., X-ray crystallography), and drug discovery efforts targeting the UPS. Its role in cancer biology has also spurred interest in developing UBC11 inhibitors as potential anticancer agents.

Beyond oncology, UBC11’s involvement in neurodegenerative diseases, where protein aggregation is a hallmark, highlights its broader pathophysiological relevance. Research on recombinant UBC11 continues to unravel its mechanistic nuances, offering insights into cellular regulation and therapeutic opportunities.
