Function

[GEMI_HUMAN] 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.[1] [2] [3] Inhibits the transcriptional activity of a subset of Hox proteins, enrolling them in cell proliferative control.[4] [5] [6] [MCIN_HUMAN] Transcription regulator required for multiciliate cell differentiation. Acts by promoting transcription of genes required for multiciliate cell formation. Probably acts in a multiprotein complex (By similarity). Plays a role in mitotic cell cycle progression by promoting cell cycle exit.
