Gene Family: Elongin complex (ELO)

Also known as : "SIII complex", "transcription elongation factor SIII complex"

Elongin complex:: The Elongin complex is a positive regulator of RNA polymerase II and and increases the rate of elongation by suppressing transient pausing along the DNA template. It is composed of a transcriptionally active subunit (A) and two regulatory subunits (B and C). The Elongin BC complex enhances the transcriptional activity of Elongin A. The Elongin BC complex also acts as an adaptor connecting cullins and SOCS box proteins. [Source: Okumura et al, 2012]
