Summary
Predicted to enable RNA polymerase II general transcription initiation factor activity and TBP-class protein binding activity. Involved in mRNA transcription by RNA polymerase II; regulation of DNA binding activity; and transcriptional start site selection at RNA polymerase II promoter. Located in nucleus. Is expressed in several structures, including embryonic/larval midgut; embryonic/larval visceral muscle cell; and extended germ band embryo. Orthologous to human GTF2B (general transcription factor IIB). [provided by Alliance of Genome Resources, Apr 2022]
