WebThe anaphase-promoting complex/cyclosome (APC/C) represents a large multisubunit E3-ubiquitin ligase complex that controls the unidirectional progression through the cell cycle by the ubiquitination of specific target proteins, marking them for proteasomal destruction. Although the APC/C's role is largely conserved among eukaryotes, its subunit composition … WebAnaphase. centromere of each chromatid pair splits. Telophase. DNA begins uncoiled chromatin and nucleolus becomes visible again.

WebIn anaphase, activation of anaphase-promoting complex (APC) induces segregation of chromosomes and exit from mitosis by catalyzing the proteolytic destruction of securin and cyclins. Because cytokinesis occurs once per cell cycle and it is coupled to the exit from mitosis, there must be some connection between the cell-cycle engine and cytokinesis. WebThe anaphase-promoting complex (APC) is a large, multiprotein complex whose E3-ubiquitin ligase activity is required for the ubiquitination of mitotic cyclins and other regulatory proteins that are targeted for destruction during cell division. The recent identification of new APC subunits and regulatory proteins has begun to reveal some of the ...
