MeSH definition : A heterotrimeric protein complex composed of 110 kDa elongin A, 18 kDa elongin B,
and 15 kDa elongin C subunits. It functions as a positive regulator of RNA POLYMERASE
II, increasing its rate of transcriptional elongation by suppressing transient pausing
along the DNA template. Elongin A is the transcriptionally active component; elongins
B and C enhance its activity.;
