an o-Glycosylated antibacterial peptide with activity against Gram-negative and Gram-positive bacteria - expressed in the fat body during the systemic immune response and is expressed in various epithelia. The expression of Dro is regulated at the transcriptional level mostly by the immune deficiency pathway - hemocytes relay an innate immune response to the blood cell reservoir: through Imd signaling and the ak/Stat pathway ligand Upd3, hemocytes act as sentinels of bacterial infection, inducing expression of the antimicrobial peptide Drosocin in respiratory epithelia and colocalizing fat body domains

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
The Dro locus (CG10816) encodes two peptides that are produced from a precursor protein by cleavage at a canonical furin cleavage site: its namesake peptide 'Drosocin', and a 22-residue peptide named 'Buletin' (corresponding to the previously uncharacterized 'Immune-induced Molecule 7', IM7).
Identified as a gene with significant level of mRNA cycling as assessed by expression analysis using high density oligonucleotide arrays with probe generated from adult heads harvested over six time points over the course of a day. Shows alteration in expression in a Clk mutant background.
Identification: Encodes a protein that is induced by immune challenge.
Ecol\lacZDpt.PR adults are pricked with a sterile needle dipped in culture pellets of various living microorganisms (distinct bacterial strains, fungal spores or hyphae). Pricking results in a low but clearly detectable expression of all antimicrobial genes and these genes are induced above the background level by specific classes of microorganism.
Glycopeptides of Dro are isolated and the range of activities of these molecules is studied.
Cloning and characterisation of Dro. 2.5kb of upstream sequence confers inducibility and tissue specificity to a transgene.
Genes encoding antibacterial peptides are regulated in a manner distinct from that of Drs, encoding the antifungal peptide.
Transcription is not strongly induced by hymenopteran parasitoids.
Dro encodes a 19-residue proline-rich inducible antibacterial peptide, which has an O-glycosylation that is necessary for its full biological activity.

Source for merge of Dro BcDNA:RH31634 was a shared cDNA ( date:030728 ).
The C-terminal peptide produced by furin cleavage from the 'Dro' precursor protein is named Buletin (Btn) after Philippe Bulet, whose dedicated efforts in the 1980s-1990s characterized many of the Drosophila AMPs including Drosocin.
