NCIt definition : Tfg3 (TFIIF) is a general stimulatory transcription initiation factor that binds to
RNA Polymerase II decreasing its affinity for non-specific DNA. Tfg3 is also a component
of the mediator complex and is important for cellular morphogenesis and actin cytoskeletal
function. Tfg3 is composed of three subunits and is similar to human ENL and AF-9
proteins. (from SWISS-PROT P35189 and NCI);
