Biolegend, 687603, Alexa Fluor® 647 anti-Histone H3.1 Phospho (Ser28) Antibody, 25tests

Histone proteins are classified into core histones (H2A, H2B, H3, H4) and linker histones (H1, H5). Core histones form an octamer, which contains two H2A-H2B dimers and one H3-H4 tetramer. Core histones are predominantly globular except for the unstructured N-terminal tails. Posttranslational modifications, such as acetylation, methylation, phosphorylation, ubiquitination, SUMOylation and ADP-ribosylation occur in histone tails. Histone modifications induce changes of chromatin structure and thereby affect the accessibility of transcription factors, nuclear proteins and enzymes to genomic DNA, resulting in gene activation or repression. It is known that histone modifications play critical roles in DNA repair, DNA replication, transcription regulation, alternative splicing and chromosome condensation and some diseases including autoimmune diseases and cancers.

RRID: AB_2616946 (BioLegend Cat. No. 687603) AB_2616947 (BioLegend Cat. No. 687604)
Structure: H3 is part of the nucleosome, comprised of an octameric complex with H2A, H2B, and H4 proteins.
Distribution: Nucleus.
Function: H3 is a core component of the nucleosome that serves to wrap and compact DNA into chromatin. Therefore, histones limit the accessibility of DNA by providing mechanisms for transcription regulation, DNA repair and replication and chromosomal stability.
Interaction: Two molecules of H3 form a heterotetramer with two molecules of H4.
