Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: carboxypeptidase activity; metallocarboxypeptidase activity.
There is experimental evidence that it is involved in the biological process: long-term memory; imaginal disc-derived wing morphogenesis; phagocytosis, engulfment.
72 alleles are reported.
The phenotypes of these alleles are annotated with 11 unique terms, many of which group under: adult segment; organ system subdivision; adult mesothoracic segment; organ system; thoracic segment; adult; sensillum; sense organ; external sensillum; cell cluster organ.
It has 8 annotated transcripts and 8 annotated polypeptides.
Protein features are: Carbohydrate-binding-like fold; Carboxypeptidase, regulatory domain; Carboxypeptidase-like, regulatory domain; Peptidase M14, carboxypeptidase A.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of moderate expression.
Peak expression observed at stages throughout embryogenesis, during late larval stages, at stages throughout the pupal period, in adult female stages.
