Function

[CDC26_HUMAN] Component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C complex acts by mediating ubiquitination and subsequent degradation of target proteins: it mainly mediates the formation of 'Lys-11'-linked polyubiquitin chains and, to a lower extent, the formation of 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains. May recruit the E2 ubiquitin-conjugating enzymes to the complex.^[1] [CDC16_HUMAN] Component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through mitosis and the G1 phase of the cell cycle.

Publication Abstract from PubMed

The multisubunit anaphase promoting complex (APC) is an essential cell-cycle regulator. Although CDC26 is known to have a role in APC assembly, its molecular function has remained unclear. Biophysical, structural and genetic studies presented here reveal that CDC26 stabilizes the structure of APC6, a core TPR protein required for APC integrity. Notably, CDC26-APC6 association involves an intermolecular TPR mimic composed of one helix from each protein.
