The function of MCM10 (minichromosome maintenance 10 replication initiation factor, Ensembl gene identifier ENSG00000065328) is as follows. Acts as a replication initiation factor that brings together the MCM2-7 helicase and the DNA polymerase alpha/primase complex in order to initiate DNA replication. Additionally, plays a role in preventing DNA damage during replication. Key effector of the RBBP6 and ZBTB38-mediated regulation of DNA-replication and common fragile sites stability; acts as a direct target of transcriptional repression by ZBTB38 (PubMed:24726359). {ECO:0000269|PubMed:11095689, ECO:0000269|PubMed:15136575, ECO:0000269|PubMed:17699597, ECO:0000269|PubMed:19608746, ECO:0000269|PubMed:24726359, ECO:0000269|PubMed:32865517}.
