Transcription elongation factor B polypeptide 1 is a protein that in humans is encoded by the TCEB1 gene.^[3]^[4]

Function

This gene encodes the protein elongin C, which is a subunit of the transcription factor B (SIII) complex. The SIII complex is composed of elongins A/A2, B and C. It activates elongation by RNA polymerase II by suppressing transient pausing of the polymerase at many sites within transcription units. Elongin A functions as the transcriptionally active component of the SIII complex, whereas elongins B and C are regulatory subunits. Elongin A2 is specifically expressed in the testis, and capable of forming a stable complex with elongins B and C. The von Hippel-Lindau tumor suppressor protein binds to elongins B and C, and thereby inhibits transcription elongation.^[5]

Interactions

TCEB1 has been shown to interact with:

TCEB2^[6]^[7]^[8]^[9] and
Von Hippel-Lindau tumor suppressor.^[7]^[9]^[10]^[11]^[12]^[13]^[14]
