Inhibits DNA replication by preventing the incorporation of MCM complex into pre-replication complex (pre-RC) . It is degraded during the mitotic phase of the cell cycle . Its destruction at the metaphase-anaphase transition permits replication in the succeeding cell cycle . Inhibits histone acetyltransferase activity of KAT7/HBO1 in a CDT1-dependent manner, inhibiting histone H4 acetylation and DNA replication licensing . Inhibits the transcriptional activity of a subset of Hox proteins, enrolling them in cell proliferative control .
Cytoplasm . Nucleus . Mainly cytoplasmic but can be relocalized to the nucleus. .
