Description | Apc1 is the largest of the subunits of the anaphase-promoting complex or cyclosome. The anaphase-promoting complex is a multiprotein subunit E3 ubiquitin ligase complex that controls segregation of chromosomes and exit from mitosis in eukaryotes [1,2]. Infection of human fibroblasts with human cytomegalovirus (HCMV) leads to cell cycle dysregulation, which is associated with the inactivation of the anaphase-promoting complex [3]. Apc1 consists of a N-terminal WD40 beta-propeller domain, a middle domain (Mid-N), a PC domain and a C-terminal domain (Mid-C) that coalesces with Mid-N to form Apc1Mid which connects Apc1-WD40 with Apc1-PC and comprises an alpha-solenoid capped by a beta-sandwich [4,5]. The N-terminal domain is essential for APC/C catalytic activity as it mediates the coactivator-induced conformational change of the APC/C which promotes UbcH10 binding [4]. |
