The HIST2H2AA3 (N-terminal) antibody specifically targets the N-terminal region of the histone H2A type 2-A3 protein, encoded by the HIST2H2AA3 gene. Histones, including H2A, are core components of nucleosomes, playing critical roles in chromatin structure and epigenetic regulation. The H2A family consists of multiple variants, with HIST2H2AA3 being a replication-dependent subtype involved in DNA packaging and transcriptional regulation. The N-terminal tail of H2A undergoes post-translational modifications (e.g., acetylation, phosphorylation, ubiquitination) that influence chromatin dynamics, DNA repair, and gene expression.
This antibody is commonly used in epigenetics and chromatin biology research to study H2A-specific modifications or localization. Its N-terminal specificity allows detection of conserved epitopes near modification sites, making it valuable for Western blotting, immunofluorescence, or ChIP-seq to investigate histone modification patterns in diseases like cancer or developmental disorders. Validation often includes reactivity testing in knockdown models or histone extraction protocols.
As HIST2H2AA3 shares high sequence homology with other H2A variants, careful controls are required to confirm target specificity. Commercial antibodies may vary in clonality (monoclonal/polyclonal) and recommended applications. Researchers should verify cross-reactivity and optimize conditions for experimental systems, as histone modifications are context-dependent and dynamically regulated.
