(Submitter supplied) Estrogen Receptor (ER) is a steroid hormone receptor that regulates epithelial genes in breast cancer. ER forms a regulatory network with the other transcription factors, FOXA1 and GATA3. GATA3 is known to be capable of specifying chromatin localization of FOXA1 and ER. GATA3 has been identified as one of the most frequently mutated genes in breast cancer. However, how GATA3 mutations impact this transcriptional network is unknown. more...

(Submitter supplied) A pioneer transcription factor, GATA3, is one of the most frequently mutated genes in breast cancer, yet the impact of these mutations is largely unknown. We generated a GATA3 mutant cell line (T47D wt/R330fs) by CRISPR. Mutation of one allele of GATA3 led to loss of binding and decreased expression at a subset of genes, including Progesterone Receptor. At other loci, associated with epithelial to mesenchymal transition, gain of binding at a novel sequence motif correlated with increased gene expression. more...
