The recombination signal sequence-binding protein RBP-2N functions as a transcriptional repressor.

Abstract excerpt

We have identified a cellular protein, RBP-2N, a presumed recombinase, as a repressor of transcription. Inhibition of transcription by RBP-2N was dependent on its DNA recognition site and was demonstrated in vitro and in vivo. This repression appears to be general, as transcription mediated by SP1 and Gal4/VP16 was inhibited by RBP-2N. The protein was purified to near homogeneity from human cells on the basis of...
