obsolete RNA polymerase II transcription factor activity, TBP-class protein binding, involved in preinitiation complex assembly https://github.com/geneontology/go-ontology/issues/16053 true TATA-binding protein binding RNA polymerase II transcription factor activity involved in preinitiation complex assembly 2011-01-20T02:53:35Z molecular_function OBSOLETE. Binding to a member of the class of TATA-binding proteins (TBP), including any of the TBP-related factors (TRFs), to facilitate the aggregation, arrangement and bonding together of proteins on RNA polymerase II promoter DNA to form the transcriptional preinitiation complex (PIC), the formation of which is a prerequisite for transcription by RNA polymerase. GO:0001129 TBP-class protein binding RNA polymerase II transcription factor activity involved in preinitiation complex assembly krc The reason for obsoletion is that this concept is partly covered by other concepts in the ontology and usage has been inconsistent.
