Transcription elongation regulator 1

Transcription elongation regulator 1, also known as TCERG1, is a is_associated_with::protein which in humans is encoded by the TCERG1 is_associated_with::gene.

Function
This gene encodes a nuclear protein that regulates transcriptional elongation and pre-is_associated_with::mRNA splicing. The encoded protein interacts with the hyperphosphorylated C-terminal domain of is_associated_with::RNA polymerase II via multiple FF domains, and with the pre-mRNA splicing factor SF1 via a WW domain. Alternative splicing results in multiple transcripts variants encoding different isoforms.

Interactions
Transcription elongation regulator 1 has been shown to interact with SF1 and is_associated_with::POLR2A.
