Enables DNA binding activity. Predicted to be involved in several processes, including RNA polymerase II preinitiation complex assembly; positive regulation of intrinsic apoptotic signaling pathway; and positive regulation of transcription initiation from RNA polymerase II promoter. Located in nucleus. Is expressed in several structures, including brain; early conceptus; genitourinary system; gut gland; and retina. Orthologous to human TAF6 (TATA-box binding protein associated factor 6). [provided by Alliance of Genome Resources, Apr 2022]
