PG - 426-31 AB - GATA-1 is a key regulator of terminal erythroid differentiation in mammals and birds. The structural and biochemical studies of human GATA-1 (hGATA-1) are limited by the difficulty of its purification in a sufficient amount. Here we describe the procedure for obtaining pure bacterial recombinant hGATA-1 in an active functional state. We demonstrate that this protein may be successfully used for preparing an affinity column, producing GATA-1-specific rabbit polyclonal antibodies, and studying DNA-protein and protein-protein interactions.
