scaf

Gene
scaf
Protein
Inactive serine protease scarface
Organism
Drosophila melanogaster
Length
655 amino acids
Function
Inactive serine protease that plays a role in germ-band retraction and dorsal closure morphogenesis in embryogenesis; contributes to amnioserosa attachment and epithelial apico-basal polarity by regulating the localization of laminin LanA on the apical side of the amnioserosa epithelium (PubMed:28628612, PubMed:20379222). Contributes to epithelial morphogenesis probably by regulating the bsk/JNK pathway, as part of a negative-feedback loop, and by modulating the cross-talk between the Egfr, bsk/JNK and dpp signal transduction pathways (PubMed:28628612, PubMed:20379222). In larval development, antagonizes the morphogenetic movements controlled by the bsk/JNK signaling including male genitalia formation and thorax development (PubMed:20379222, PubMed:20530545, PubMed:25737837).
Similarity
Belongs to the peptidase S1 family.
