Abstract
Histone lysine crotonylation (Kcr) is a novel hydrophobic histone acylation modification, and we recently report its crucial roles in neural differentiation. However, it is still unclear how histone Kcr involve in early neural commitment. Here, we systematically investigate the H3K9cr landscapes during neuroectodermal differentiation of pluripotent P19 embryonal carcinoma cells (ECCs). We reveal that the genome-wide changes in H3K9cr favor neural fate specification, and identify potential co-factors binding H3K9cr. We also uncover that H3K9cr collaborates with H3K9ac to regulate gene expression changes. Our results provide novel insights into the epigenetic mechanisms underlying neural commitment.
