Research Abstract

Depletion of Mcm10 by siRNA inhibited origin firing, not fork progression. Using truncated mutants, I found Mcm10 interacted with Mcm2-7 through the intrinsically disorder domain. In addition, the genetical analyses showed that the conserved domain was essential for DNA replication. On the contrary, the Mcm2-7-interacting domain contributed to the retention of Mcm10 onto chromatin.
