UBE2C also known as ubiquitin-conjugating enzyme E2C or UBCH10 is an enzyme that plays a role in the ubiquitination process. Its molecular mass is approximately 20 kDa. UBE2C is an E2 ubiquitin-conjugating enzyme actively involved in marking proteins for degradation through the ubiquitin-proteasome system. It facilitates the transfer of ubiquitin to target proteins cooperating with E3 ligases. UBE2C shows expression in various tissues with high levels observed in proliferating cells such as those found in tumors.

Biological function summary

UBE2C is involved in cell cycle regulation by targeting specific proteins for ubiquitination and degradation. It collaborates with the anaphase-promoting complex/cyclosome (APC/C) an important E3 ligase complex ensuring the proper progression of the cell cycle especially during the metaphase-anaphase transition. Through this action UBE2C aids in maintaining genomic stability by preventing the accumulation of proteins that can interfere with cell division.

Pathways

The role of UBE2C is integral in the cell cycle and ubiquitin-proteasome pathways. The enzyme participates in the proper execution of the metaphase-anaphase transition and degradation of cell cycle regulators like cyclin B. UBE2C interacts with proteins such as CDC20 a co-activator of APC/C to ensure accurate coordination of cell division events. Its function in the ubiquitin-proteasome pathway emphasizes its role in maintaining protein homeostasis.

UBE2C's dysfunction or overexpression associates with cancer development and progression. Overexpression of UBE2C has been observed in various cancers including breast cancer and prostate cancer and may contribute to tumorigenesis by disrupting cell cycle control. UBE2C can interact with oncoproteins such as MYC further linking its dysregulation to cancer pathways. Understanding the relationships between UBE2C and cancer may offer insights into therapeutic targets for tumor treatment.
