The gene 14-3-3ε is referred to in FlyBase by the symbol Dmel\14-3-3ε (CG31196, FBgn0020238). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: protein binding; protein heterodimerization activity. There is experimental evidence for 12 unique biological process terms, many of which group under: single-organism developmental process; biological regulation; cellular component organization or biogenesis; cell cycle; cell cycle process; regulation of growth; response to DNA damage stimulus; localization; response to UV; determination of adult lifespan. 39 alleles are reported. The phenotypes of these alleles are annotated with: posterior crossvein; eye; oocyte; pole cell; anterior crossvein; segmental nerve branch SNa of A1-7; eye photoreceptor cell; intersegmental nerve branch ISNb of A1-7; ommatidium; cycle 14 embryo. It has 4 annotated transcripts and 4 annotated polypeptides. Protein features are: 14-3-3 domain; 14-3-3 protein; 14-3-3 protein, conserved site. Summary of modENCODE Temporal Expression Profile: Very high expression at all stages of development. Summary of FlyAtlas Anatomical Expression Data: High levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval/adult fat body, larval/adult salivary gland, larval trachea, adult female reproductive system, adult male reproductive system, larval/adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1628694_a_at completely aligns to an exonic region common to each of the 4 FlyBase-annotated transcript isoforms of 14-3-3epsilon. Gene sequence location is 3R:14068253..14075030.

In syncytial embryos, 14-3-3ε protein localizes to rapidly dividing nuclei. During mitosis, it is retained in nuclei. During cellularization, nuclear expression diminishes and membrane expression appears. During gastrulation, a low level of staining is observed in ectodermal cells. High levels are transiently observed in various tissues. At stages 7 and 8, expression is observed in several invaginating furrows, the ventral midline cells, and the dorsal epidermal cells. At stages 9 and 10, prominant staining is observed in the ventral neurogenic region extending in a 4-5 cell wide region from the midline. 14-3-3ε protein is highly enriched in the central and peripheral nervous systems. It is observed in the cytoplasm of neurons.
Summary of FlyAtlas Anatomical Expression Data: High levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult central nervous system, adult crop, larval/adult midgut, larval/adult hindgut, larval/adult Malpighian tubules, adult heart, larval/adult fat body, larval/adult salivary gland, larval trachea, adult female reproductive system, adult male reproductive system, larval/adult carcass.

14-3-3ε has been cloned and characterised. Genetic studies suggest that 14-3-3ε functions in multiple receptor tyrosine kinase pathways, acting downstream or parallel to phl, but upstream of aop and phyl, two nuclear factors involved in Ras85D signalling.
The autosomal "FLP-DFS" technique (using the P{ovoD1-18}P{FRT(whs)}P{hsFLP} chromosomes) has been used to identify the specific maternal effect phenotype for the zygotic lethal mutation. 14-3-3ε gene expression during oogenesis is not critical to embryonic development, but the gene function may be essential for fertilisation and/or completion of meiosis.
