CC -!- FUNCTION: Component of the NC2 complex which represses RNA polymerase CC II transcription through binding to SPT15/TBP and thereby inhibiting CC the assembly of the preinitiation complex. The NC2 complex may also CC mediate transcriptional activation from TATA-driven promoters through CC association with SPT15/TBP. {ECO:0000269|PubMed:12237409, CC ECO:0000269|PubMed:8948634, ECO:0000269|PubMed:9023340, CC ECO:0000269|PubMed:9096360}. CC -!- SUBUNIT: Component of the NC2 (negative cofactor 2) complex composed of CC BUR6 and NCB2. The NC2 complex associates with SPT15/TBP. Interacts CC with SPT15/TBP. {ECO:0000269|PubMed:8948634, CC ECO:0000269|PubMed:9023340, ECO:0000269|PubMed:9096360}.
