Positive transcription elongation factor b (P-TEFb) is definitely a RNA polymerase

Positive transcription elongation factor b (P-TEFb) is definitely a RNA polymerase II carboxyl-terminal domain (Pol II CTD) kinase that phosphorylates Ser2 from CD55 the CTD and promotes the elongation phase of transcription. the transcription of GV oocytes globally. Moreover using fluorescence in situ hybridization in absence of CDK9 kinase activity the production of ribosomal RNAs… Continue reading Positive transcription elongation factor b (P-TEFb) is definitely a RNA polymerase
