Functioni

Possesses antifungal activity and is active against a relatively broad spectrum of filamentous fungi (PubMed:8808632, PubMed:12872120). It inhibits spore germination at high concentrations and at low concentrations delays growth of hyphae which subsequently exhibit abnormal morphology (PubMed:7806546). Spz C-106 in the hemolymph controls expression of the antifungal peptide by acting as a ligand of Tl and inducing an intracellular signaling pathway (PubMed:8808632). Part of a psh-dependent Toll pathway, which may function in activating the systematic immune response in response to localized melanization of the tracheal system (PubMed:18854145).4 Publications

Expressioni

Tissue specificityi

Synthesized in the fat body and is secreted into the blood (PubMed:9736738). In hemolymph 6 hours after immune challenge, levels of expression increase for first 24 hours and persist for the following three weeks (PubMed:9736738). In larvae, expressed in the visceral branches and posterior spiracles of the trachea (PubMed:22022271).2 Publications

Inductioni

Up-regulated by septic injury caused by the Gram-positive bacteria M.luteus and the fungus C.albicans, and by M.luteus or E.faecalis-derived peptidoglycans and by B.subtilis or A.oryzae proteases (PubMed:19590012). Up-regulated by Gram-negative bacteria in the respiratory epithelium (PubMed:22022271). Up-regulated in the trachea and fat body in response to tracheal melanization, either by spontaneous melanization or melanization resulting from infection by bacteria (E.coli and M.luteus) or the fungus B.bassiana (PubMed:18854145).3 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
