PHOSPHORYLATION OF HISTONES AND USES THEREOF

摘要

Phosphorylation of histones was observed at certain tyrosine residues which have not been associated with epigenetic modification. These sites include H2B Tyr37, H4 Tyr88 and Tyr51 and H3 Tyr99. Kinases responsible for the phosphorylation as well as downstream genes regulated by such phosphorylation were also identified. Antibodies that are specific to such phosphorylated histones have been generated, which are useful for detecting the phosphorylation and related events. With such findings, the present disclosure provides compositions and methods for disease diagnosis, prognosis and therapy selection, in particular for cancer, obesity and diabetes.
