Abstract:
Nuclear factor I (NFI) proteins constitute a large family of DNA binding proteins. These proteins promote the initiation of adenovirus replication and regulate the transcription of viral and cellular genes. The binding sites for NFI have been reported in a wide variety of promoters, and they exhibit flexibility in their sequences. To clarify the DNA binding site of NFI-A, one of the NFI proteins, we performed a polymerase chain reaction-mediated random site selection, and determined the optimal sequence as 5'-TTGGCANNNN(G/T)CCA(G/A)-3'.
