Protein
Serine protease grass
Gene
grass
Organism
Drosophila melanogaster (Fruit fly)
Status
Functioni
Endopeptidase (By similarity). Plays a key role in innate immunity by activating the Toll pathway in response to fungal and Gram-positive bacterial infections, presumably downstream of pattern-recognition receptors (PRR), such as PGRP-SA, GNBP1 and GNBP3, and upstream of spz processing enzyme SPE (PubMed:16631589, PubMed:18724373).By similarity2 Publications

Disruption phenotypei
Results in increased susceptibility to fungal or Gram-positive bacterial infection and failure to induce the expression of the Toll pathway-activated antifungal peptide Drs (PubMed:18724373). siRNA-mediated knockdown results in increased susceptibility to Gram-positive bacterial infection and severe reduction in the expression of the antifungal peptide Drs (PubMed:16631589). In a protease psh mutant background, complete loss of Drs induction and increased susceptibility to Gram-positive bacterial infection (PubMed:18724373).2 Publications
