Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: aspartate 1-decarboxylase activity.
There is experimental evidence that it is involved in the biological process: visual behavior.
216 alleles are reported.
The phenotypes of these alleles are annotated with: tarsal segment; trident; wing vein; puparium; adult cuticle.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Pyridoxal phosphate-dependent decarboxylase; Pyridoxal phosphate-dependent transferase, major domain; Pyridoxal phosphate-dependent transferase, major region, subdomain 1; Pyridoxal phosphate-dependent transferase, major region, subdomain 2.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of very low expression.
Peak expression observed at stages throughout the pupal period.
