H3-3B (H3.3 histone B)

Gene

• Entrez ID: 3021
• Gene name: H3.3 histone B
• Gene symbol: H3-3B
• Synonyms (NCBI Gene): BRYLIB2, H3-3A, H3.3B, H3F3B
• Chromosome: 17
• Chromosome location: 17q25.1
• Summary: Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA
