Protein Name & Synonyms:
TAF1B, MGC:9349, RAF1B, RAFI63, SL1, TAFI63, TATA box-binding protein-associated factor RNA polymerase I subunit B
PBS with 0.02% sodium azide, 50% glycerol, pH7.3.
Initiation of transcription by RNA polymerase I requires the formation of a complex composed of the TATA-binding protein (TBP) and three TBP-associated factors (TAFs) specific for RNA polymerase I. This complex, known as SL1, binds to the core promoter of ribosomal RNA genes to position the polymerase properly and acts as a channel for regulatory signals. This gene encodes one of the SL1-specific TAFs. Multiple transcript variants encoding different isoforms have been found for this gene.
