Identification of Xenopus laevis egg extract fraction stimulating somatic DNA replication through LC-MSMS

ABSTRACT: In several metazoans the number of active replication origins in embryonic nuclei is higher than in somatic ones, ensuring rapid genome duplication during synchronous embryonic cell divisions. High replication origin density can be restored by somatic nuclear reprogramming. However, mechanisms underlying high replication origin density formation coupled to rapid cell cycles are poorly understood. Here, we characterized a fraction of Xenopus egg extract able to stimulate somatic DNA replication.
