This domain family is found in eukaryotes, and is typically between 138 and 153 amino acids in length. The family is found in association with Pfam:PF00493. Mini-chromosome maintenance (MCM) proteins are essential for DNA replication. These proteins use ATPase activity to perform this function.

1: The ATPase activity of MCM2-7 is dispensable for pre-RC assembly but is required for DNA unwinding. Ying CY, Gautier J; EMBO J. 2005;24:4334-4344. PMID:16369567
