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.[2] Transcription factor II E is encoded by the
GTF2E1 and
GTF2E2 genes.[3][4][5][6] TFIIE is thought to be involved in
DNA melting at the
promoter: it contains a zinc ribbon motif that can bind single stranded DNA.[7]
