The APC/C (anaphase-promoting complex/cyclosome) is an E3 ubiquitin ligase that targets specific substrates for degradation by the 26S proteasome. APC/C activity depends on two cofactors, namely Cdc20 (cell division cycle 20) and Cdh1, which select the appropriate targets for ubiquitination. it is well established that APC/C is a target of the SAC (spindle assembly checkpoint) during mitosis and has critical roles in controlling the protein levels of major regulators of mitosis and DNA replication. in addition, recent studies have suggested new cell-cycle-independent functions of APC/C in non-mitotic cells and specifically in neuronal structure and function. Given the relevant functions of APC/C in cell proliferation and neuronal physiology, modulating APC/C activity may have beneficial effects in the clinic.
