Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
An electronic pipeline based on InterPro domains suggests that it has the molecular function: ATP binding; ATP-dependent helicase activity; nucleic acid binding.
There is experimental evidence that it is involved in the biological process: germ-line stem cell maintenance; oogenesis; germ cell development; germ-line stem cell division.
31 alleles are reported.
The phenotypes of these alleles are annotated with 12 unique terms, many of which group under: organ system; multicellular structure; anatomical structure; female germline cyst; egg; germarium; cytoplasmic part; chorion; spectrosome; organelle.
It has one annotated transcript and one annotated polypeptide.
Protein features are: DNA/RNA helicase, DEAD/DEAH box type, N-terminal; Maternal tudor protein.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of very low expression.
Peak expression observed during early pupal stages, in stages of adults of both sexes.
