Flies expressing GNBP1dsRNA.Scer\UAS under the control of Scer\GAL4da.G32 show no detectable defects, indicating that GNBP1 is not essential for development. Flies expressing GNBP1dsRNA.Scer\UAS under the control of Scer\GAL4da.G32 rapidly succumb to infection by Gram-positive bacteria (E.faecalis, S.aureus or M.luteus). Flies expressing GNBP1dsRNA.Scer\UAS under the control of Scer\GAL4da.G32 are resistant to fungal infection (A.fumigatus or B.bassiana). Flies expressing GNBP1dsRNA.Scer\UAS under the control of Scer\GAL4da.G32 are resistant to infection by Gram-negative bacteria (P.carotovorum.carotovorum).
GNBP1RNAi.UAS, Scer\GAL4da.G32 has abnormal immune response phenotype, non-enhanceable by PGRP-SAseml
Scer\GAL4da.G32/GNBP1RNAi.UAS is a non-enhancer of abnormal immune response phenotype of PGRP-SAseml
Flies expressing GNBP1dsRNA.Scer\UAS under the control of Scer\GAL4da.G32 in a PGRP-SAseml background show the same degree of susceptibility to M.luteus as either PGRP-SAseml single mutant flies or flies expressing GNBP1dsRNA.Scer\UAS under the control of Scer\GAL4da.G32 in a wild-type background.
RT-PCR confirms that overexpression of the P{UAS-GNBP1-IR} construct leads to a significant decrease in GNBP1 transcripts.
