Screening of functional maternal-specific chromatin regulators in early embryonic development of zebrafish

Abstract

The early stages of embryonic development rely on maternal products for proper regulation. However, screening for functional maternal-specific factors is challenging due to the time- and labor-intensive nature of traditional approaches. Here, we combine a computational pipeline and F0 null mutant technology to screen for functional maternal-specific chromatin regulators in zebrafish embryogenesis and identify Mcm3l, Mcm6l, and Npm2a as playing essential roles in DNA replication and cell division. Our results contribute to understanding the molecular mechanisms underlying early embryo development and highlight the importance of maternal-specific chromatin regulators in this critical stage. Computational tools and F0 null mutant analysis allow the identification of the maternal chromatin regulators Mcm3l, Mcm6l, and Npm2a in zebrafish embryogenesis, which are essential for DNA replication and cell division.
