General description
Histone H2A is one of four components of the core nucleosomal structure. Histones undergo a number of post-translational modifications (PTM) in response to various stimuli that may induce changes in the structure of the nucleosome and hide or expose DNA sequences. The degree of ubiquitylation at DNA damage sites is regulated at multiple levels in order to generate proper DNA damage response. Uncontrolled ubiquitylation of histones can lead to unscheduled transcriptional silencing and generate defects in DNA damage checkpoint activation and cell cycle arrest. The RNF168 E3 ligase ubiquitylates H2A at K13, K15, which in turn triggers the recruitment of DNA damage response proteins, such as 53BP1 and BRCA1 to DNA break sites. USP51, a deubiquitinating enzyme, removes H2AK13, 15ub following DNA repair. Depletion of USP51 can result in elevated levels of H2AK13, 15ub on chromatin and cause delays in disassembly of proteins at DNA damage foci.
Specificity
Clone EDL H2AK15-4 specifically recognizes histone H2A monoubiquitylated at Lys15, but not unmodified H2A. Does not recognize di-ubiquitin, K63 and K27 linked di-ubiquitin species.
Immunogen
KLH-conjugated branched peptide corresponding to the ubiquitination site on human H2AK15.
Application
Anti-H2AK15ub, clone EDL H2AK15-4, Cat. No. MABE1119, is a highly specific mouse monoclonal antibody, that targets H2A ubiquitylated at Lys15 and has been tested in Immunocytochemistry and Western Blotting.

Human 53BP1 is primarily known as a key player in regulating DNA double strand break (DSB) repair choice; however, its involvement in other biological process is less well understood. Here, we report a previously uncharacterized function of 53BP1 at heterochromatin

How chromatin dynamics is regulated to ensure efficient DNA repair remains to be understood. Here, we report that the ubiquitin-specific protease USP11 acts as a histone deubiquitinase to catalyze H2AK119 and H2BK120 deubiquitination. We showed that USP11 is physically associated
