Protein
Negative cofactor 2 complex subunit alpha
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Component of the NC2 complex which represses RNA polymerase II transcription through binding to SPT15/TBP and thereby inhibiting the assembly of the preinitiation complex. The NC2 complex may also mediate transcriptional activation from TATA-driven promoters through association with SPT15/TBP.
Similarity
Belongs to the NC2 alpha/DRAP1 family.
