Binding of the nuclear factor-Y complex (NF-Y) to the inverted CCAAT-box interferes with transcription activation through nucleosome reorganization. The three homologous proteins forming the zinc-fingers and homeoboxes (ZHX) family interact with the activation domain of NF-Ya to repress transcription. Each ZHX-protein contains two generic C2H2 zinc-fingers (ZNF1 and ZNF2) followed by five homeodomains. Although the proteins have been related to the occurrence of certain cancers, the function ...Expand abstract
