In the field of molecular biology and proteomics, few structures are as fundamental as the core histones. Among these, histone h4 peptide sequence analysis provides critical insights into the architecture of chromatin. As someone who frequently works with biochemical standards and research-grade proteins, I have found that understanding the precise arrangement of these amino acids is essential for interpreting experimental outcomes in structural biology.
The Structural Foundation of Histone H4
Histone H4 is a core component of the nucleosome, the primary unit of chromatin in eukaryotic cells. Its importance is underscored by its high degree of conservation across species. Structurally, it functions alongside H2A, H2B, and H3 to form the octameric spool around which DNA winds. When examinin Histone H4 peptide (1-21) human ≥90% (HPLC) g the histone h4 peptide sequence, we often focus on the N-terminal tail, which is a major site for post-translational modifications.
For researchers utilizing synthetic variants, the amino acid residues 1-21 of histone H4 are frequently used as a standard. The canonical sequence for this N-terminal region is often represented as: MSGRGKGGKGLGKGGAKRHRK. In some specific applications, this may be extende A peptide substrate for Histone 4 R3 methyltransferases. The peptide corresponds toamino acid residues 1-21 of histone H4. d to SGRGKGGKGLGKGGAKRHRKV to encompass the full reach of the tail domain.
Technical Insights and Research Applications
The study of this protein often involves complex methodologies. For instance, the solid-phase peptide synthesis of H4R40C(1–42) has become a standard protocol for those investigating the interaction between histones and their regulatory partners.

The structural basis for this interaction involves a binding pocket that stabilizes the peptide, a mechanism critical for chromatin assembly.
* Sequence Variations: While the primary sequence is remarkably stable, researchers often look for specific markers like H4K91ub (monoubiquitination at Lys-92) to understand how the protein responds to environmental stressors or DNA damage.
* Div 3C9C: Structural Basis of Histone H4 Recognition by p55 erse Fragments: Depending on the experimental goal, one might source Histone H4 (8-30) peptides or longer chains to test methyltransferase activity or antibody specificity.
Why the Sequence Matters
The sequence of H4 is not merely a string of letters; it dictates the functional landscape of the genome. The HIST2H4A gene / cDNA is a protein-coding gene that ensures the consistent production of this vital protein. Whether one is evaluating Histone H4, NP_778224.1/, ISGLIYEETR for mass spectrometry calibration or using it as a substrate for enzymatic assays, the integrity of the peptide is paramount.
When reviewing Histone H4 is an important protein in the structure and function of chromatin, it is clear that its role as a core histone protein remains a cornerstone of cellular biology. The C-terminal region, characterized by the sequence ALKRQGRTLYGFGG, completes the globular domain, providing stability to the nucleosome particle.
