Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Its molecular function is unknown.
There is experimental evidence that it is involved in the biological process: apposition of dorsal and ventral imaginal disc-derived wing surfaces; chitin-based cuticle attachment to epithelium; open tracheal system development; chitin-based embryonic cuticle biosynthetic process.
13 alleles are reported.
The phenotypes of these alleles are annotated with 11 unique terms, many of which group under: organ system; multicellular structure; organ system subdivision; non-connected developing system; tracheal system; thoracic segment; portion of tissue; late extended germ band embryo; acellular anatomical structure; anatomical structure.
It has 3 annotated transcripts and 3 annotated polypeptides.
Protein features are: Zona pellucida sperm-binding protein.
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.
