Mitogen-activated protein kinase kinase kinase 7; Component of a protein kinase signal transduction cascade. Mediator of TGF-beta signal transduction. Responsible for activation of the JNK MAPK pathway (basket, bsk and hemipterous, hep) in response to LPS. Component of the NF-kappa-B pathway; relish-mediated JNK inhibition involves proteasomal degradation of Tak1; certain targets of Relish that are induced during immune responses may facilitate destruction of Tak1 and switch off the JNK cascade. Participates in diverse roles such as control of cell shape and regulation of apoptosis.

Nuclear factor NF-kappa-B p110 subunit; Plays a key role in the humoral immune response. Rel-p68 subunit translocates to the nucleus where it binds to the promoter of the Cecropin A1 gene and probably other antimicrobial peptide genes. I-kappa-B kinase complex (IKKbeta and key) and PGRP-LC are essential signaling components in transmitting the lipopolysaccharide (LPS) signal leading to cact degradation for NF-kappa-B (rel) activation. Part of a Toll-related receptor pathway that functions in the apoptosis of unfit cells during cell competition. May be part of a NF-kappa-B and Tollo sig [...]

TAK1-associated binding protein 2 (Tab2) encodes a protein with an ubiquitin binding domain. It interacts with the product of Tak1, a MAP kinase kinase kinase involved the activation of the immune deficiency, JNK and Grindelwald-Eiger pathways.

ATP binding; JUN kinase kinase kinase activity; protein kinase activity. It is involved in the biological process described with: activation of JUN kinase activity.

Fas-associated death domain protein; Component of the IMD signaling pathway and is required for the host defense against Gram-negative bacteria. Interacts with Dredd, promotes cleavage of Dredd and is necessary and sufficient for enhancing Dredd-induced apoptosis.

Tak1-like 2 (Takl2) encodes a putative serine-threonine kinase with similarity to the kinase encoded by Tak1. It has a mild wound closure phenotype in larval wound healing assays.

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 [...]

Cylindromatosis, isoform D; Lys63-specific deubiquitinase activity; thiol-dependent ubiquitin-specific protease activity; ubiquitinyl hydrolase activity, acting on linear ubiquitin.

Ubiquitin-conjugating enzyme variant 1A (Uev1A) encodes a conserved protein that contributes to ubiquitin conjugating enzyme activity, but not catalytically, since it lacks the conserved cysteine residue essential for ubiquitin conjugation. It regulates genomic integrity, IMD pathway-mediated innate immunity, JNK-pathway mediated cell death and tumor invasion.
