New evidence indicates that termination of transcription is an important regulatory step, closely related to transcriptional interference and even transcriptional initiation. However, how this occurs is poorly understood. Recently, in vivo analysis of transcriptional termination for the human beta-globin gene revealed a new phenomenon--co-transcriptional cleavage (CoTC). This primary cleavage event within beta-globin pre-messenger RNA, downstream of the poly(A) site, is critical for efficient...Expand abstract
