Target Background

Function
Histone H2BB is a core component of the nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to cellular machinery that requires DNA as a template. Histones play a crucial role in regulating transcription, DNA repair, DNA replication, and chromosomal stability. DNA accessibility is regulated through a complex set of post-translational modifications of histones, also known as the histone code, and nucleosome remodeling.

Acetyl-HIST1H2BB (K5) Antibody is a primary antibody specifically designed to recognize the acetylation of lysine 5 (K5) on Histone H2B type 1-B (HIST1H2BB). This histone variant is part of the core nucleosome structure and its acetylation status is associated with transcriptional regulation and chromatin accessibility. The antibody targets the peptide sequence surrounding the acetylated lysine 5 residue of Human Histone H2B type 1-B . Detection of this specific post-translational modification provides researchers with information about chromatin states and epigenetic regulation in cellular processes.

  • ChIP (Chromatin Immunoprecipitation): To identify genomic regions associated with acetylated H2B

This range of applications makes the antibody versatile for investigating how histone acetylation correlates with gene expression, cell cycle progression, DNA repair, and various nuclear processes.

How does Acetyl-HIST1H2BB (K5) compare with other histone H2B acetylation markers?

Acetyl-HIST1H2BB (K5) represents one of several acetylation sites on histone H2B. While Acetyl-HIST1H2BB (K5) targets lysine 5, other antibodies such as those targeting Acetyl-K20 recognize different acetylation positions that may have distinct biological functions . The specificity for K5 makes this antibody valuable for studying targeted epigenetic mechanisms. Research indicates that different acetylation marks on histone H2B may be associated with distinct chromatin states and functional outcomes. For instance, histone H2B variants have undergone substantial divergence during evolution, suggesting specialized functions within different cellular contexts and organisms .

How can Acetyl-HIST1H2BB (K5) Antibody be used to investigate chromatin state transitions during cellular differentiation?
