This gene encodes a protein which interacts with the carboxy-terminus of transcription initiation factor TFIIF, a transcription factor which regulates elongation as well as initiation by RNA polymerase II. The protein may also represent a component of an RNA polymerase II holoenzyme complex. Alternative splicing of this gene results in two transcript variants encoding 2 different isoforms.[7]

Interactions

CTDP1 has been shown to interact with WD repeat-containing protein 77,[8] GTF2F1[6] and POLR2A.[9]
