SPT5 subunit of Pol II binds the RNA triphosphatase (RTP) (R-HSA-77073) [Homo sapiens]

Reaction
Summation

The capping enzyme interacts with the Spt5 subunit of transcription elongation factor DSIF. This interaction may couple the capping reaction with promoter escape or elongation, thereby acting as a "checkpoint" to assure that capping has occurred before the polymerase proceeds to make the rest of the transcript.
