Elongation, termination of transcription, and RNA processing are interconnected, presumably to ensure their proper coordination,

Elongation factors
I.    hSPT5	To recruit the 5’ -capping enzyme to the CTD tail of polymerase
II.   TAT-SF1	To recruits components of the splicing machinery to polymerase with a Ser-2 phosphorylated tail
