TATA box-binding protein-associated factor RNA polymerase I subunit A, TAF1A, RNA polymerase I-specific TBP-associated factor 48 kDa, TAFI48, BP-associated factor 1A, Transcription factor SL1, Transcription initiation factor SL1/TIF-IB subunit A
Component of the transcription factor SL1/TIF-IB complex, which is involved in the assembly of the PIC (preinitiation complex) during RNA polymerase I-dependent transcription. The rate of PIC formation probably is primarily dependent on the rate of assoc
