Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: protein phosphatase type 1 regulator activity.
There is experimental evidence that it is involved in the biological process: establishment or maintenance of polarity of follicular epithelium; establishment or maintenance of polarity of larval imaginal disc epithelium; negative regulation of cell proliferation.
13 alleles are reported.
The phenotypes of these alleles are annotated with: eye; wing disc; trichogen cell; mesothoracic tergum.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Leucine-rich repeat.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression.
Peak expression observed within 00-06 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period, in stages of adults of both sexes.
