Chemical proteomics reveals a γH2AX-53BP1 interaction in the DNA damage response
DNA double-strand break repair involves phosphorylation of histone variant H2AX ('γH2AX'), which accumulates in foci at sites of DNA damage. In current models, the recruitment of multiple DNA repair proteins to γH2AX foci depends mainly on recognition of this 'mark' by a single protein, MDC1. However, DNA repair proteins accumulate at γH2AX sites without MDC1, suggesting that other 'readers' of...
متن کاملFunctional interaction between Epstein-Barr virus replication protein Zta and host DNA damage response protein 53BP1.
Epstein-Barr virus (EBV; human herpesvirus 4) poses major clinical problems worldwide. Following primary infection, EBV enters a form of long-lived latency in B lymphocytes, expressing few viral genes, and it persists for the lifetime of the host with sporadic bursts of viral replication. The switch between latency and replication is governed by the action of a multifunctional viral protein Zta...
متن کاملThe γH2AX DNA damage assay from a drop of blood
DNA double-strand breaks (DSB) and blocked replication forks activate the DNA damage response (DDR), a signaling pathway marked by phosphorylation of histone 2AX (H2AX). The phosphorylated form, γH2AX, accumulates at the site of damage and can be detected as foci by immunocytochemistry. Therefore, γH2AX is a sensitive and robust biomarker of DNA damage, notably DSB. Cells from peripheral blood ...
متن کاملQuantitative Proteomics Reveals That Hsp90 Inhibition Preferentially Targets Kinases and the DNA Damage Response*
Despite the increasing importance of heat shock protein 90 (Hsp90) inhibitors as chemotherapeutic agents in diseases such as cancer, their global effects on the proteome remain largely unknown. Here we use high resolution, quantitative mass spectrometry to map protein expression changes associated with the application of the Hsp90 inhibitor, 17-(dimethylaminoethylamino)-17-demethoxygeldanamycin...
