MSH: An RNA POLYMERASE II specific transcription factor. It may play a role in transcriptional activation of gene expression by interacting with the TATA-BOX BINDING PROTEIN component of TRANSCRIPTION FACTOR TFIID.,NCI: A protein complex that is required for RNA polymerase II-dependent transcription of DNA. This complex is composed of transcription initiation factor IIA subunits 1 and 2 and is involved in the stabilization of the larger preinitiation complex.
