Target data

Function

Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. Required for checkpoint-mediated arrest of cell cycle progression in response to low doses of ionizing radiation and for efficient repair of DNA double strand breaks (DSBs) specifically when modified by C-terminal phosphorylation.

    Immunoprecipitation - Anti-Histone H2A.X antibody [EPR895] - Nuclear Marker (ab124781)

    Histone H2A.X was immunoprecipitated using 5ug of ab124781 from 200ul of HeLa whole cell extract lysate diluted to 0.5mg/ml in RIPA and 50ul of Protein G magnetic beads. No antibody was added to the control (-).
