Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Its molecular function is unknown.
There is experimental evidence that it is involved in the biological process: dsRNA transport.
10 alleles are reported.
No phenotypic data is available.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Saposin; Saposin B; Saposin type A; Saposin-like; Saposin-like type B, 1; Saposin-like type B, 2.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of high expression.
Peak expression observed within 00-18 hour embryonic stages, during late larval stages, at stages throughout the pupal period, in stages of adults of both sexes.
