Web24 jul. 2024 · MCMs can be phosphorylated by multiple kinases and these phosphorylation events are involved not only in DNA replication but also cell cycle progression and checkpoint response. Dysfunctional phosphorylation of MCMs appears to correlate with the occurrence and development of cancers. WebIn eukaryotes, MCM heterohexamer is phosphorylated by CDC7 and CDK, which displaces Cdc6 and recruits MCM10. MCM10 cooperates with MCM2-7 in the recruitment of Cdc45. Cdc45 then recruits key components of the replisome; the replicative DNA polymerase α and its primase. DNA replication can then begin. [7]

WebThe loading of MCM complexes to origins of replication licenses these origins for activation by replication firing factors during the S phase ( 43 ).
