Histone H2A is one of the 5 main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N terminal tail H2A is involved with the structure of the nucleosomes of the ′beads on a string′ structure.
Recognizes Histone H2A.X phosphorylated at Ser139.
peptide (C-KATQA[pS]QEY) corresponding to amino acids 134-142 of human histone H2A.X
