Specificity
This antibody recognises GATA3, also known as Trans-acting T-cell-specific transcription factor GATA-3 or GATA-binding factor 3. The protein is a member of the GATA family of transcription factors, which has received its name from binding DNA sequences containing the GATA consensus motif 5'-[AT]GATA[AG]-3' (uniprot P15976).GATA3 has been shown to play a critical role in T cell development and the differentiation of T helper 2 (Th2) cells. In addition, GATA3 has been implied to have tissue specific functions such as a regulatory role in the development of the mammary gland epithelium and skin tissue. Aberrant GATA3 levels have been identified in a variety of cancers including breast cancer. Indeed, GATA3 has become a marker for certain breast cancer types and GATA3 antibodies are commonly used for the immunohistochemical evaluation of breast cancer samples.
