Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: ATP-dependent DNA helicase activity.
Based on sequence similarity, it is predicted to be involved in the biological process: transcription initiation from RNA polymerase II promoter.
3 alleles are reported.
The phenotypes of these alleles are annotated with: trichogen cell; mesothoracic tergum.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Transcription Factor IIF, Rap30/Rap74, interaction; Transcription initiation factor IIF, beta subunit; Transcription initiation factor IIF, beta subunit, subgroup; Winged helix-turn-helix transcription repressor DNA-binding.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderate expression.
Peak expression observed within 00-06 hour embryonic stages.
