Apc5 Subunit, Anaphase-Promoting Complex-Cyclosome

A subunit of the anaphase-promoting complex whose primary function is to provide structural support for the catalytic and substrate-recognition modules of the complex. Apc5, along with Apc4, tethers the tetratricopeptide-coactivator binding subcomplex to the main structural subunit, Apc1.
