Abstract:
:The discovery of the three eukaryotic nuclear RNA polymerases paved the way for serious biochemical investigations of eukaryotic transcription and the identification of eukaryotic transcription factors. Here we describe this adventure from our vantage point, with a focus on the hunt for factors that regulate elongation by RNA polymerase II.

abstract::Argonaute (Ago) proteins mediate silencing of nucleic acid targets by small RNAs. In fission yeast, Ago1, Tas3 and Chp1 assemble into a RITS complex, which silences transcription near centromeres.
