The gene nervy is referred to in FlyBase by the symbol Dmel\nvy (CG3385, FBgn0005636). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: sequence-specific DNA binding transcription factor activity. There is experimental evidence that it is involved in the biological process: axon guidance; dendrite morphogenesis; chaeta morphogenesis; muscle organ development. 12 alleles are reported. The phenotypes of these alleles are annotated with: medial longitudinal fascicle; ventral nerve cord; lateral longitudinal fascicle; mechanosensory sensory organ; presumptive embryonic/larval central nervous system; abdominal segmental nerve; abdominal intersegmental nerve. It has 4 annotated transcripts and 4 annotated polypeptides. Protein features are: Eight-Twenty-One; NHR2-like; Nervy; TAFH/NHR1; Zinc finger, MYND-type. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of very low expression. Peak expression observed at stages throughout embryogenesis, during early larval stages, at stages throughout the pupal period, in adult male stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: larval/adult salivary gland. Expression at moderate levels in the following post-embryonic organs or tissues: larval/adult central nervous system. Comments on Affy2 ProbeSet: ProbeSet 1623977_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of nvy. Gene sequence location is 2R:20163258..20178607.

nvy is expressed in a complex and dynamic pattern. It is restricted to precursors of the central and peripheral nervous system. At certain stages, nvy is expressed in more cells or at higher levels in thoracic segments than in abdominal segments. These stages are separated by stages in which the expression pattern is the same in all segments. In later embryos, most of the nvy-expressing cells are in the posterior compartments of segments. nvy was shown to be induced by ubiquitous Ubx expression. nvy expression in various homeotic mutant backgrounds was also described.

dsRNA has been made from templates generated with primers directed against this gene. RNAi of nvy results in increased arborization of ddaD and ddaE neurons. RNAi also causes defects in muscle, defects in dendrite morphogenesis and reproducible defects in da dendrite development.
nvy couples cAMP-PKA signaling to plexA to regulate Sema-1a-mediated axon repulsion. nvy and Sema-1a function in the same signaling pathway but have opposing effects. nvy acts downstream of Sema-1a to regulate repulsive axon guidance.
The expression of nvy in a subset of delaminating neuroblasts during the early stages of neurogenesis suggest a role for nvy in neuroblast determination.
