Histone H2B type 1-L (HIST1H2BL)
The protein contains 126 amino acids for an estimated molecular weight of 13952 Da.
Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. (updated: April 1, 2015)

MAPPING
By analysis of a YAC contig from chromosome 6p22-p21.3, Albig and Doenecke (1997) characterized a second cluster of 16 histone genes, including H2B/c, located 2 Mb centromeric to the major histone gene cluster. By genomic sequence analysis, Marzluff et al. (2002) determined that the histone gene cluster on chromosome 6p22-p21, which they called histone gene cluster-1 (HIST1), contains 55 histone genes, including HIST1H2BL.GENE FUNCTION
