Ideally this entry shall become one comprehensive and continuous article. Bulleted lists, for instance, were only used because it is impossible to automatically integrate independent facts into a continuous text.
Much of the current information on this page has been automatically compiled from Pubmed.
This precompiled information serves as a substrate and matrix to embed your contributions, but it is by no means the final word - Homo sapiens can do much better!

Thus, Sharkregulates the JNK signaling pathway leading to Dpp expression in LE cells[1].
We have found that flies bearing a Sharktyrosine kinase gene mutation, shark(1), exhibit a DC-defective phenotype[1].
Furthermore, constitutive activation of the Dpp pathway throughout the epidermis fails to rescue the shark(1) DC defect, suggesting that Shark may function in additional pathways in the LE and/or lateral epithelium[1].
During Drosophila embryogenesis, Shark is expressed exclusively by ectodermally derived epithelia and is localized preferentially to the apical surface of these cells [2].
Consistent with these observations, Ddok mutant embryos exhibit decreased levels of tyrosine phosphorylated Shark at the cell periphery of LE and epidermal cells [3].
Using a yeast two-hybrid screen, the unique Drosophila homolog of the downstream of kinase (Dok) family, Ddok, was identified by its ability to bind SharkSH2 domains in a tyrosine phosphorylation-dependent fashion [3].
In cultured S2 embryonic cells, Ddok tyrosinephosphorylation is Src dependent; Shark associates with Ddok and Ddok localizes at the cell cortex, together with a portion of the Shark protein [3].
