Known as Shark kinase this signaling protein is required for dorsal closure upstream of Dpp - also required during oogenesis for dorsal-appendage morphogenesis

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Interacts with drpr; this is required for the recruitment of drpr and glial cells to severed axons and for the phagocytosis of axonal debris by glial cells following axon injury.

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

shark transcripts are expressed most strongly in 0-12hr embryos and in imaginal discs.
Shark protein is first detected at the end of gastrulation in cells destined to form the ectoderm. It is most prominent in the cephalic furrow and along the midline and is limited to the apical surfaces of the epithelia. During germ band extension when the proctodeum first becomes discernable, Shark is expressed apically in its epithelial cells. It is also observed in the cells that are forming the stomodeum. The stomodeum gives rise to the foregut, atrium, pharynx, and oesophagus, all of which express Shark until late embryogenesis. Similarly, the hindgut expressed Shark through its development. Several other ectodermally derived tissues express Shark while they maintain their epithelial character, including the stomatogastric nervous system, the frontal air sac, the tracheal system, gnathal structures, and the salivary glands. In general, Shark is expressed exclusively by ectodermally derived epithelia and is localized preferentially at the apical surface of these cells.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

shark is required for embryonic dorsal closure.
Flies carrying a mutation in shark have a defective dorsal closure phenotype.
