The GATA2 (Phospho-Ser401) antibody is a specialized tool used to detect the transcription factor GATA2 when phosphorylated at serine residue 401. GATA2. a member of the GATA family of zinc-finger proteins, plays critical roles in hematopoiesis, stem cell maintenance, and vascular development. It regulates gene expression by binding to DNA motifs in promoters/enhancers of target genes. Phosphorylation at Ser401. located in the C-terminal domain, is a post-translational modification implicated in modulating GATA2 activity, stability, or interactions with co-regulators. This modification may influence cellular processes such as hematopoietic differentiation, immune response, or endothelial cell function.
The antibody is typically validated in applications like Western blotting, immunofluorescence, or ChIP-seq to study GATA2 phosphorylation dynamics under specific conditions (e.g., cytokine stimulation, stress signaling). Researchers use it to explore how Ser401 phosphorylation correlates with diseases like leukemia, myelodysplastic syndromes, or vascular disorders. Specificity is confirmed using knockout controls or phosphatase-treated samples. Understanding GATA2 phospho-regulation provides insights into mechanisms of transcriptional control in development and pathology, making this antibody valuable for both basic and translational research.
