P-TEFb is a general transcription factor that regulates transcription elongation through phosphorylation of the C-terminal tail domain (CTD) of RNA polymerase II (RNAP II).

P - TEFb是一个普通的转录因子，它通过磷酸化rna聚合酶ii (RNAP II) C -末端尾巴结构域(CTD)来调节转录延伸。

For example, RNA polymerase II is found concentrated at the promoters of thousands of genes, causing much interest in the field to shift focus to the role of elongation in regulating gene expression.

例如，RNA聚合酶ii发现集中在成千上万个基因的促销员，导致在该领域的极大兴趣，在调节基因表达的重点转移到伸长的作用。
