|Application ||WB, IHC, IF|
|Reactivity||Human, Mouse, Rat|
|Calculated MW||15404 Da|
|Other Names||Histone H31, Histone H3/a, Histone H3/b, Histone H3/c, Histone H3/d, Histone H3/f, Histone H3/h, Histone H3/i, Histone H3/j, Histone H3/k, Histone H3/l, HIST1H3A, H3FA|
|Target/Specificity||A synthetic acetylated peptide corresponding to residues surrounding Lys 27 of Histone H3T was used as immunogen. The antibody only detects Histone H3T acetylated on Lysine 27.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Histone-H3T Antibody Acetyl (K27) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||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.|
|Cellular Location||Nucleus. Chromosome.|

Changes in chromatin structure play a large role in the regulation of transcription in eukaryotes (1). The nucleosome is the primary building block of chromatin, and is made up of four core histone proteins (H2A, H2B, H3 and H4) (2). Acetylation of core histones regulates gene expression (2). Histone H3 is primarily acetylated at lysines 9, 14, 18, and 23 (3,4). Acetylation at lysine 9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms (3,4). . H3t (H.34) differs from the consensus mammalian H3 structure by four amino acid residues and it is mainly expressed in testicular cells. H3t encoding gene maps to chromosome 1 (1q42), unlike the majority of the human histone genes that form cluster on chromosome 6 and outside of replication-dependent H3 genes (5).
