Research Abstract

Mitochondrial DNA (mt-DNA) is packed into a highly organized DNA-protein complex called the mitochondrial nucleoid (mt-nucleoid). Division of mt-nucleoid is necessary for mt-DNA distribution into daughter mitochondria. However, little is understood about the molecular mechanisms that regulate the mt-nucleoid division. In this study, we showed that a mitochondrial RCC1(Regulator of chromosome condensation 1)-like protein of P. polycephalum was involved in the mt-nucleoid division by controlling of the association of mt-nucleoids and cristae. We also identified a human mitochondrial RCC1-like protein (hmtRCC1). The down regulation analysis of hmtRCC1 showed that this protein might be involved in the mt-nucleoid division.
