obsolete TFIIB-class transcription factor binding involved in viral suppression of host transcription initiation from RNA polymerase II promoter (obsolete GO:0039605)
OBSOLETE. Selective and non-covalent interaction of a viral protein with a member of the TFIIB-class of host transcription factors, which contributes to the viral-suppression of assembly of the RNA polymerase II preinitiation complex (PIC) at an RNA polymerase II promoter region of a host DNA template.
