Transcription profiling of mouse FOG-1-binding defective mutant of GATA-1, ER-GATA-1(V205G), was expressed in GATA-1-null G1E cells


ABSTRACT: Identification of genes regulated by GATA-1 independent of the cofactor FOG-1. Experiment Overall Design: A conditionally activated FOG-1-binding defective mutant of GATA-1, ER-GATA-1(V205G), was expressed in GATA-1-null G1E cells. Transcipt levels were compared in cells untreated or treated with estradiol to activate the GATA-1 mutant.

The GATA-1-interacting protein Friend Of GATA-1 (FOG-1) is essential for the proper transcriptional activation and repression of numerous GATA-1 target genes. Although FOG-1-independent activation by GATA-1 has been described, all known examples of GATA-1-mediated repression are FOG-1 dependent. In the GATA-1-null G1E cell line, estrogen receptor ligand binding domain (ER) chimeras of either wild-type GATA-1 or a FOG-1-binding defective mutant of GATA-1 repressed several genes similarly upon act  ...[more]
