Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: DNA-dependent ATPase activity.
There is experimental evidence that it is involved in the biological process: female meiosis; transcription termination, DNA-dependent; microtubule anchoring at centrosome; spermatogenesis.
27 alleles are reported.
The phenotypes of these alleles are annotated with: onion stage spermatid; trichogen cell; centrosome; individualization stage spermatid.
It has one annotated transcript and one annotated polypeptide.
Protein features are: DEAD-like helicase; Helicase, C-terminal; SNF2-related.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression.
Peak expression observed within 00-06 hour embryonic stages, in adult female stages.
