Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: N-acylneuraminate-9-phosphate synthase activity.
An electronic pipeline based on InterPro domains suggests that it is involved in the biological process: carbohydrate biosynthetic process.
4 alleles are reported.
The phenotype of these alleles is annotated with: mesothoracic tergum.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Aldolase-type TIM barrel; Antifreeze-like/N-acetylneuraminic acid synthase C-terminal; N-acetylneuraminic acid synthase, N-terminal; SAF domain.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of extremely low expression.
Peak expression observed within 06-24 hour embryonic stages, during early larval stages, during early pupal stages.
