Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: trehalase activity.
Based on sequence similarity, it is predicted to be involved in the biological process: trehalose metabolic process.
18 alleles are reported.
The phenotypes of these alleles are annotated with: trichogen cell; mesothoracic tergum.
It has 6 annotated transcripts and 6 annotated polypeptides.
Protein features are: Glycoside hydrolase, family 37; Glycoside hydrolase, family 37, conserved site; Six-hairpin glycosidase-like.
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 18-24 hour embryonic stages, during early larval stages, at stages throughout the pupal period, in stages of adults of both sexes.
