Product Details


CUSABIO put the phospho-GATA3 (S308) monoclonal antibody DNA sequence into the plasmid, which was subsequently transfected into the cell line for expression. Immunizing mice with the synthetic phospho-peptide corresponding to residues surrounding Ser 308 of human GATA3 produced the phospho-GATA3 (S308) monoclonal antibody. The recombinant phospho-GATA3 (S308) monoclonal antibody was obtained after the product was purified using affinity chromatography. It's a rabbit IgG antibody. This phospho-GATA3 (S308) antibody has undergone ELISA, WB, and IHC quality testings. It is reactive with human samples. This anti-pSer308-GATA3 antibody may be used to address the functional role of GATA3 phosphorylation.

GATA3 is mostly expressed in T lymphocytes and is essential for both early thymic T-cell development and functional differentiation of naive CD4 T cells into Th2 cells. GATA3, a T-cell transcription factor, has been found to influence Th2 T-cell development in a number of investigations. It also plays a role in mammary gland development and the preservation of luminal epithelial cells' differentiated state. Posttranslational modifications, the proteasome pathway, and phosphorylation all can regulate GATA3 activity. In ER-positive breast cancer cells, phosphorylation of GATA3 at Ser308 has previously been utilized as a marker of proteasomal turnover.
