摘要

NF-E2 is an erythroid-specific transcription factor required for expression of several erythroid-specific genes. By Far-Western blotting and yeast two-hybrid assay, we demonstrate that p45, the large subunit of NF-E2, is capable of binding to a specific set of WW domain-containing proteins, including the ubiquitin ligase hRPF1. This binding is mediated through the interaction between the WW domains and a PY motif located within the amino- terminal region of p45. Interestingly, the carboxyl-terminal domain of mammalian RNA polymerase II binds a similar set of WW domains to which p45 interacts with. We discuss the data in terms of possible new pathways through which the processes of transcriptional regulation by NF-E2 could be regulated in erythroid and megakaryote cells.
