Summary Information
Automatically generated summary See sections below for more information	The gene chiffon is referred to in FlyBase by the symbol Dmel\chif (CG5813, FBgn0000307). It is a protein_coding_gene from Drosophila melanogaster. An electronic pipeline based on InterPro domains suggests that it has the molecular function: zinc ion binding; DNA binding. There is experimental evidence that it is involved in the biological process: chorion-containing eggshell formation; eggshell chorion gene amplification. 22 alleles are reported. The phenotypes of these alleles are annotated with: chorion; eye; trichogen cell; scutellar bristle. It has 3 annotated transcripts and 3 annotated polypeptides. Protein features are: AT hook, DNA-binding motif; Zinc finger, DBF-type. 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 at stages throughout embryogenesis, in adult female stages. Summary of FlyAtlas Anatomical Expression Data: Two or more Affy2 ProbeSets identify exons of this gene. This is a summary of the tissue expression peaks exhibited in at least one of these ProbeSets. Expression at moderate levels in the following post-embryonic organs or tissues: adult eye, larval/adult central nervous system, adult crop, larval Malpighian tubules, larval fat body, larval/adult salivary gland, larval trachea, adult female reproductive system, larval carcass. Gene sequence location is 2L:16342430..16352600.
External Summaries
Phenotypic Description from the Red Book (Lindsley & Zimm 1992)
Gene/Allele symbols may differ from current usage	chif: chiffon (T. Schupbach) Female sterile, homozygous females lay eggs which have thin, fragile chorions and remain unfertilized.

Additional Descriptive Data
	Abundant chif transcripts are detected in nurse cells in egg chambers. Low levels of chif transcripts are detected in follicle cells. chif transcripts are detected in egg chambers and very early embryos on northern blots indicating that they are maternally supplied to the embryo.

Additional comments	Sequences corresponding to the 5' end of release 2 CG18115 overlap the 3' end of release 3 chif transcript CG5813-RA. (FlyBase Genome Annotators, 2002-2003) Release 1 annotation CG5817 overlaps part of the release 3.2 annotation for chif (CG5813). (FlyBase, 1996-)
Other Comments
	The Hrp59 protein binds preferentially to a subset of mRNAs, including chif mRNA. (Kiesler et al., 2005) Hypomorphic mutations in chif cause thin, fragile chorions and female sterility, and eliminate chorion gene amplification. Null alleles have the additional phenotypes of rough eyes and thin thoracic bristles; phenotypes often associated with disruption of the normal cell cycle. (Landis and Tower, 1999) chif is involved in processes in addition to chorion gene amplification. (Landis and Tower, 1995) Mutations at the chif locus cause defects in midoogenesis. (Schupbach and Wieschaus, 1991) 5 alleles are discussed but are not named. (Ashburner et al., 1990)
