What's a GeneRIF?
  1. The results suggest that Abp1 prevents pervasive RNAPII transcription of repetitive DNA elements (ie, Tf2 and rDNA repeats) from internal cryptic sites.
    Title: The fission yeast CENP-B protein Abp1 prevents pervasive transcription of repetitive DNA elements.
  2. we describe the impact of silencing and clustering on the mobility of an endogenous Tf2 element. Deletion of genes such as set1(+) or abp1(+) that both alleviate silencing and clustering, result in a corresponding increase in mobilization. Furthermore, expression of constitutively active Sre1, a transcriptional activator of Tf2 elements, also alleviates clustering and induces mobilization
