How does GATA-1 regulate red cell genes like globin or the Epo receptor ? Once we identify the functional domains of the GATA-binding proteins , we hope to learn what proteins GATA-1 binds to in the basic transcription machinery or in chromatin.
 protein: Epo receptor; DNA: globin; DNA: red cell genes; protein: GATA-binding proteins; protein: GATA-1; protein: GATA-1
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2".
