CC -!- FUNCTION: Recruits TFIIH to the initiation complex and stimulates the
CC RNA polymerase II C-terminal domain kinase and DNA-dependent ATPase
CC activities of TFIIH. Both TFIIH and TFIIE are required for promoter
CC clearance by RNA polymerase. {ECO:0000269|PubMed:1956398,
CC ECO:0000269|PubMed:1956404}.
CC -!- SUBUNIT: Tetramer of two alpha and two beta chains (PubMed:1956398).
CC Interacts with FACT subunit SUPT16H (PubMed:10792464). Interacts with
CC ATF7IP (PubMed:19106100). Interacts with SND1 (PubMed:7651391).

CC -!- DISEASE: Trichothiodystrophy 6, non-photosensitive (TTD6) [MIM:616943]:
CC A form of trichothiodystrophy, a disease characterized by sulfur-
CC deficient brittle hair and multisystem variable abnormalities. The
CC spectrum of clinical features varies from mild disease with only hair
CC involvement to severe disease with cutaneous, neurologic and profound
CC developmental defects. Ichthyosis, intellectual and developmental
CC disabilities, decreased fertility, abnormal characteristics at birth,
CC ocular abnormalities, short stature, and infections are common
CC manifestations. There are both photosensitive and non-photosensitive
CC forms of the disorder. TTD6 patients do not manifest cutaneous
CC photosensitivity. Inheritance pattern has been reported to be autosomal
CC recessive. {ECO:0000269|PubMed:26996949}. Note=The disease is caused by
CC variants affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the TFIIE beta subunit family.
CC {ECO:0000255|PROSITE-ProRule:PRU00682}.
