Abstract

The MCM (mini-chromosome maintenance) complex is the core of the eukaryotic replicative helicase and comprises six proteins, Mcm2-Mcm7. In humans, a variant form of the complex has Mcm2 replaced by the MCM-BP protein. Recent results suggest that a similar complex exists in fission yeast with an essential role in DNA replication and cell cycle progression. Here, we describe the purification and subunit composition of the fission yeast MCMMcb1 complex. Using newly generated temperature-sensitive alleles, we show that loss of MCMMcb1 function leads to accumulation of DNA damage, checkpoint activation and cell cycle arrest, and provide evidence for a role for MCMMcb1 in meiosis.
