Intestinal gene expression in different physiological conditions There is not condition-dependent expression data available for this gene.
Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: chitin binding; structural constituent of peritrophic membrane.
An electronic pipeline based on InterPro domains suggests that it is involved in the biological process: chitin metabolic process.
5 alleles are reported.
No phenotypic data is available.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Chitin binding domain.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of low expression.
Peak expression observed within 12-18 embryonic stages, at stages throughout the pupal period.
