Protein immune deficiency; Essential for the imd/NF-kappa-B (Imd) humoral and epithelial immune response to Gram-negative bacteria. Functions as an adapter protein that transduces immunity signals from the activation of pathogen recognition receptors (PRRs) by bacterial infection to the Imd signaling pathway. Binding of diaminopimelic acid-type (DAP-type) bacterial peptidoglycans (PGN) causes multimerization or clustering of PGRP receptors which activate the Imd cascade probably by recruiting imd, Fadd and Dredd to the receptor complex. Once in proximity, Dredd cleaves imd in a Fadd-de [...]

Diptericin A (DptA) encodes an immune inducible antibacterial peptide with activity against Gram-negative bacteria. It is expressed in the fat body during the systemic immune response and in various epithelia. Its expression is regulated at the transcriptional level by the immune deficiency pathway; Belongs to the attacin/sarcotoxin-2 family.

Diptericin B (DptB) encodes an immune inducible antibacterial peptide with activity against Gram-negative bacteria. It is expressed in the fat body during the systemic immune response and in various epithelia. Its expression is regulated at the transcriptional level by the immune deficiency pathway.

Probable sulfite oxidase, mitochondrial; Molybdenum ion binding; sulfite oxidase activity; heme binding; molybdopterin cofactor binding. It is involved in the biological process described with: sulfur compound metabolic process; nitrate assimilation; oxidation-reduction process.

Delta-1-pyrroline-5-carboxylate synthase; Glutamate-5-semialdehyde dehydrogenase activity; glutamate 5-kinase activity; delta1-pyrroline-5-carboxylate synthetase activity. It is involved in the biological process described with: oxidation-reduction process; proline biosynthetic process; In the C-terminal section; belongs to the gamma-glutamyl phosphate reductase family.

Peptidoglycan-recognition protein LC; Major activator of the imd/Relish pathway and is likely to encode a pattern recognition molecule for the humoral immune response. Required for Relish processing and nuclear translocation following proteolytic cleavage. Involved in the response to lipopolysaccharide (LPS) and peptidoglycan of Gram-negative bacteria. The different isoforms probably display different recognition capabilities to various microbial patterns. [Isoform x]: Mediates the response to LPS, peptidoglycan and Gram-negative bacteria; Belongs to the N-acetylmuramoyl-L-alanine amid [...]

Myd88 (Myd88) encodes an adaptor protein involved in in the Toll pathway functioning downstream of the product of Tl and upstream of the product of tub. Toll pathway is a signaling cascade that plays a key role in various developmental and immune processes, notably embryonic dorsoventral patterning and regulation of antimicrobial peptides.

Unpaired 3 (upd3) encodes a "cytokine" (secreted protein) of the Unpaired family that can bind and activate the JAK-STAT receptor encoded by dome. It is induced in hemocytes or in the intestine upon damage to regulate the repair response in these tissues through JAK-STAT activation.

Peptidoglycan recognition protein LB (PGRP-LB) encodes a secreted protein with an amidase activity that scavenges DAP-type peptidoglycan, a cell wall component found on Gram-negative bacteria and certain Gram positive bacteria. It negatively regulates the immune deficiency pathway; Belongs to the N-acetylmuramoyl-L-alanine amidase 2 family.
