obsolete TFIIIB-type transcription factor activity true RNA polymerase III recruiting transcription factor activity This term was obsoleted because it represents a gene product. OBSOLETE. Binding to an RNA polymerase III (Pol III) complex, typically composed of seventeen subunits, and with another protein, macromolecule, or complex, permitting those molecules to function in a coordinated way, Once recruited to an RNA polymerase III promoter by one or more other transcription factors, binds to DNA, recruits RNA polymerase III and facilitates the transition from the closed to the open complex. molecular_function GO:0001026 2010-08-23T12:24:31Z krc
