Evan Worden Phd Mechanisms Of Crosstalk Between Histone Ubiquitination And Methylation

Evan Worden Phd Mechanisms Of Crosstalk Between Histone Abstract. methylation of histone h3 k79 by dot1l is a hallmark of actively transcribed genes that depends on monoubiquitination of h2b k120 (h2b ub) and is an example of histone modification cross talk that is conserved from yeast to humans. we report here cryo em structures of dot1l bound to ubiquitinated nucleosome that show how h2b ub. Topic: mechanisms of crosstalk between histone ubiquitination and methylationpresenter: evan worden, cynthia wolberger's laboratory, johns hopkins universit.

The cryo em structure of a six protein core compass subcomplex, which can methylate h3k4 and be stimulated by h2b ub, bound to a ubiquitinated nucleosome, is reported here and provides a framework for understanding mechanisms of trans histone cross talk and the dynamic role of h 2b ubiquitination in stimulating histone methylation. expand.
