Summary
Enables DNA binding activity. Involved in chromatin assembly or disassembly; 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 H2BC11 (H2B clustered histone 11); H2BC12 (H2B clustered histone 12); and H2BC13 (H2B clustered histone 13).
