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. Belongs to the TFIIE alpha subunit family. Note: This description may include information from UniProtKB.
Biological Process: RNA elongation from RNA polymerase II promoter; snRNA transcription from RNA polymerase II promoter; transcription from RNA polymerase II promoter; transcription initiation from RNA polymerase II promoter
LTP: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
