What pLDDT means and how to read it

Function

Component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through the cell cycle (PubMed:11739784, PubMed:18485873, PubMed:27120157, PubMed:27509861). Together with the RING-H2 protein ANAPC11, forms the catalytic component of the E3 ubiquitin ligase complex (PubMed:11739784, PubMed:18485873, PubMed:27120157, PubMed:27509861). APC/C 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 (PubMed:11739784, PubMed:18485873). APC/C…

Subunit structure

Component of the anaphase promoting complex/cyclosome (APC/C), composed of ANAPC1, ANAPC2, CDC27/ANAPC3, ANAPC4, ANAPC5, CDC16/ANAPC6, ANAPC7, CDC23/ANAPC8, ANAPC10, ANAPC11, CDC26/ANAPC12, ANAPC13, ANAPC15 and ANAPC16 (PubMed:25043029, PubMed:26083744, PubMed:27120157, PubMed:27509861). APC/C associates with CDC20 to form the CDC20-APC/C complex, which is crucial for metaphase/anaphase…
