    Summary
    Enables DNA binding activity. Involved in chromatin organization; negative regulation of transcription by RNA polymerase II; and postreplication repair. Part of nucleosome and replication fork protection complex. Orthologous to several human genes including H2BC1 (H2B clustered histone 1); H2BC10 (H2B clustered histone 10); and H2BC11 (H2B clustered histone 11).
