Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: receptor activity.
There is experimental evidence that it is involved in the biological process: instar larval development.
25 alleles are reported.
The phenotypes of these alleles are annotated with: embryonic/larval trachea; embryonic/larval tracheal system; embryonic/larval cuticle.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Fibronectin type III domain; Fibronectin, type III; Immunoglobulin-like fold; von Willebrand factor, type C.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of very low expression.
Peak expression observed within 12-18 embryonic stages, at stages throughout the pupal period.
