Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: U2 snRNA binding; protein binding; snRNA stem-loop binding; U1 snRNA binding.
There is experimental evidence that it is involved in the biological process: oogenesis; regulation of alternative nuclear mRNA splicing, via spliceosome.
17 alleles are reported.
The phenotypes of these alleles are annotated with: ovary; egg chamber; germarium.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Nucleotide-binding, alpha-beta plait; RNA recognition motif domain.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderately high expression.
Peak expression observed within 00-12 hour embryonic stages.
