Predicted to enable identical protein binding activity. Predicted to be involved in regulation of transcription, DNA-templated. Predicted to be located in cytosol; microtubule cytoskeleton; and nucleolus. Predicted to be part of RNA polymerase transcription factor SL1 complex. Predicted to be active in nucleoplasm. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and sensory organ. Orthologous to human TAF1D (TATA-box binding protein associated factor, RNA polymerase I subunit D). [provided by Alliance of Genome Resources, Apr 2022]
