U7 snRNA acts as a transcriptional regulator interacting with an inverted CCAAT sequence-binding transcription factor NF-Y.

Abstract

An inverted CCAAT sequence is recognized by both transcription factors NF-Y and DNA/RNA binding protein YB-1. In the process of examining the effect of nuclear RNA on an inverted CCAAT-containing promoter of MDR1 gene, we found that U7 snRNA inhibits NF-Y and suppresses the promoter activity both in vitro and in NG108-15 tumor cells. Analysis using a… (More)
