Elongin C is a protein that in humans is encoded by the ELOC gene.^[5]^[6]

Function

Elongin C 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.^[7]

Interactions

TCEB1 has been shown to interact with:

TCEB2^[8]^[9]^[10]^[11] and
Von Hippel-Lindau tumor suppressor.^[9]^[11]^[12]^[13]^[14]^[15]^[16]
