a transcriptional regulator central in Th2 cell differentiation. Inhibits breast cancer growth and pulmonary breast cancer metastasis. Represses INK4C transcription, constrains luminal progenitor cell expansion, and suppresses luminal tumorigenesis in the mammary gland. High GATA3 and low INK4C expression predicts a favorable patient outcome in luminal A type breast tumors. IFN-lambda1 (IL-29) inhibits GATA3 expression and suppresses Th2 responses in human T cells. GATA3 haploinsufficiency leads to HDR (hypoparathyroidism, deafness, and renal dysplasia) syndrome. Two alternatively spliced human isoforms have been described.
