Molecular function

basal RNAP II transcription machinery binding

Binding to a component of the basal transcription machinery for RNA polymerase II which is composed of the RNA polymerase II core enzyme, a multisubunit eukaryotic nuclear RNA polymerase typically composed of twelve subunits, and the basal RNA polymerase II transcription factors, the minimal set of factors required for formation of the preinitiation complex (PIC) by the RNA polymerase.

Note that the definition of basal, or general, transcription factors has typically been done at a small number of well characterized activator-independent promoters. At an activator-dependent promoter, one or more additional factors are generally required in addition to the basal factors.
