RNA polymerase II complex binding obsolete basal RNA polymerase II transcription machinery binding https://github.com/geneontology/go-ontology/issues/16062 true molecular_function basal RNAP II transcription machinery binding krc OBSOLETE. 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. GO:0001099 This term was obsoleted because it is equivalent to RNA polymerase II complex binding ; GO:0000993. 2010-11-24T12:54:33Z
