This is histone H3 (1-21), dimethylated at Lys9. Lysine 9 methylation is related to transcriptional silence chromatin. Histone H3 is mono- and dimethylated at Lys 9 located in the silencing domain in euchromatin, while histone H3 trimethylated at this residue is located in the pericentromeric heterochromatin.
