The gene Chorion protein 16 is referred to in FlyBase by the symbol Dmel\Cp16 (CG6533, FBgn0000356). It is a protein_coding_gene from Drosophila melanogaster. It is reported to have molecular function: structural constituent of chorion. It is reported to be involved in the biological process: eggshell chorion assembly. 4 alleles are reported. No phenotypic data is available. It has one annotated transcript and one annotated polypeptide. Protein features are: Chorion S16. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of no expression detected. Peak expression observed in adult female stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult ovary. Comments on Affy2 ProbeSet: ProbeSet 1629380_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of Cp16. Gene sequence location is 3L:8725044..8725699.

The six major chorion bands are dramatically reduced in follicles of Mcm6[K1214], mus101K451 and fs(1)A1059K1 mutants. No reduction of major chorion bands is seen in swa6 although some affects are seen in higher molecular weight components.

The Cp15, Cp16, Cp18 and Cp19 genes of the chorion cluster have been characterized in D.melanogaster, D.subobscura, D.virilis and D.grimshawi. The temporally specific follicular expression of Cp15, Cp16, Cp18 and Cp19 and gene organization has been conserved. A highly conserved DNA region exists downstream of Cp16 and in the 5' flanking DNA.
The fourth of four chorion-protein genes in a 6-kb sequence; encodes S16-1, a 16,000-dalton chorion protein. Temporal and spatial distribution of expression described (Parks and Spradling, 1987).
