TFIIE recruits TFIIH to the initiation complex and stimulates the RNA polymerase II C-terminal domain kinase and DNA-dependent ATPase activities of TFIIH. Both TFIIH and TFIIE are required for promoter clearance by RNA polymerase. Transcription factor II E is encoded by the GTF2E1 and GTF2E2 genes. TFIIE is thought to be involved in DNA melting at the promoter: it contains a zinc ribbon motif that can bind single stranded DNA.
