Background
UBE2C is one of several ubiquitin conjugating enzymes participating in the E3 anaphase-promoting complex (APC/C). UBE2C is involved in the control of multiple stages of the cell cycle including inactivation of the mitotic spindle assembly checkpoint. UBE2C facilitates ubiquitin-dependent proteasomal degradation by initiating K11-linked ubiquitin chains on APC/C substrates. Research studies show that UBE2C expression is low in normal tissues, but its expression is dramatically upregulated in tumors derived from tissues such as lung, breast, and prostate. Overexpression of UBE2C in many types of solid tumors has been attributed to genomic amplification of the UBE2C locus and research studies have suggested that inhibition of UBE2C activity may have therapeutic potential.
