CC -!- FUNCTION: Stabilizes TBP binding to an archaeal box-A promoter. Also
CC responsible for recruiting RNA polymerase II to the pre-initiation
CC complex (DNA-TBP-TFIIB). {ECO:0000256|HAMAP-Rule:MF_00383}.
CC -!- SIMILARITY: Belongs to the TFIIB family.
CC {ECO:0000256|ARBA:ARBA00010857, ECO:0000256|HAMAP-Rule:MF_00383}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:EMA38691.1}.
