The APC is an E3 ubiquitin ligase that marks target proteins for degradation by the 26S proteasome. The irreversibility of proteolysis is utilized by cells to give the cell cycle directionality. WebThe anaphase-promoting complex/cyclosome (APC/C) represents a large multisubunit E3-ubiquitin ligase complex that controls the unidirectional progression through the cell cycle by the ubiquitination of specific target proteins, marking them for proteasomal destruction.
