Protein tamozhennic; Has an essential role during oogenesis and embryogenesis, perhaps in modulating the levels of nuclear import of additional proteins. Modulates the nuclear import of dorsal (dl), Dif and male specific lethal 1 (msl-1). Negatively regulates nuclear import of dl and controls the accumulation of dl in the nucleus after immune challenge.

Protein abrupt; Expression is vital for development; may be involved in transcriptional regulation. In embryos, muscle specific expression is required for segmental nerve b (SNb) motoneuron target recognition within ventral longitudinal muscles. Has a role in establishing and maintaining embryonic muscle attachments, adult sensory cell formation (macrochaetae) and morphogenesis of adult appendages (legs, antenna aristae and male external genitalia). Has a role in the morphogenesis of the class I dendritic neurons: selective expression of ab in class I da neurons plays a pivotal role in [...]

Tyrosine-protein kinase Fer; Tyrosine-protein kinase which is required during embryogenesis for formation of the actin cable in leading edge cells of the dorsal epidermis and for the timely progression of dorsal closure. May play a role in regulation of adherens junctions and cell adhesion through phosphorylation of the beta-catenin arm.

Beta Spectrin (beta-Spec) encodes an essential protein that interacts with the product of alpha-Spec to form a heterotetramer. The product of beta-Spec is typically associated with the plasma membrane. It functions in a lipoprotein pathway that delivers dietary fat to the larval fat body for storage. It is also believed to function in asymmetric division of germ line stem cells via cytoplasmic structures called spectrosomes and fusomes.

Protein flightless-1; May play a key role in embryonic cellularization by interacting with both the cytoskeleton and other cellular components. Alternatively, it may play a structural role in indirect flight muscle. Vital for embryonic development; Belongs to the villin/gelsolin family.

Fructose-bisphosphate aldolase; May take part in developmental stage-specific or tissue -specific sugar-phosphate metabolisms. Protein acts on two substrates fructose 1,6-bisphosphate and fructose 1-phosphate (like other class I aldolases).

Netrin-A; Netrins control guidance of CNS commissural axons at the midline and peripheral motor axons to their target muscles.

E3 ubiquitin-protein ligase Su(dx); E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Down-regulates Notch/N signaling pathway, probably by promoting Notch ubiquitination, endocytosis and degradation. Involved in wing growth and leg joint formation.

E3 ubiquitin-protein ligase highwire; Atypical E3 ubiquitin-protein ligase which specifically mediates ubiquitination of threonine and serine residues on target proteins, instead of ubiquitinating lysine residues (By similarity). Shows esterification activity towards both threonine and serine, with a preference for threonine, and acts via two essential catalytic cysteine residues that relay ubiquitin to its substrate via thioester intermediates (By similarity). Required in the presynaptic motoneuron to down-regulate the levels of wnd and restrain synaptic terminal growth at the neuromu [...]
