背景介绍

DNA-directed RNA polymerase II subunit RPB1(POLR2A), is part of the core element of the basic RNA polymerase II transcription mechanism. During transcription elongation, Pol II moves on the template as the transcript elongates. Elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of Pol II largest subunit (RPB1), which serves as a platform for the assembly of factors that regulate transcription initiation, elongation, termination, and mRNA processing.
