Gene Summary
TGF-β activated kinase 1 (Tak1) encodes a MAP kinase kinase kinase that functions downstream of the products of imd, Fadd and Diap2. It also functions upstream of the IKK complex in the Imd pathway, a pathway regulating the antibacterial response and other less characterized cellular processes. Upon activation the product of imd, the product of Tak1 can also activate the JNK pathway at the level of the JNK Kinase encoded by bsk in certain cell types. It is also an intracellular signaling component of the Grindelwald-Eiger pathway. [Date last reviewed: 2019-03-14] (FlyBase Gene Snapshot)

Gene Group (FlyBase)
NON-RECEPTOR TKL KINASES -
Non-receptor tyrosine kinase-like (TKL) kinases are a diverse group of intracellular serine-threonine protein kinases with sequence similarity to tyrosine kinases (TK) but lacking TK-specific motifs.
Pathway (FlyBase)
IMD SIGNALING PATHWAY CORE COMPONENTS -
The immune deficiency (Imd) pathway primarily mediates the humoral immune response to Gram-negative bacteria. Activation of the Imd pathway by diaminopimelic acid-type peptidoglycan initiates a signaling cascade that ultimately results in the release of the NFκB-like factor Rel from auto-inhibition and its translocation into the nucleus to activate the transcription of antimicrobial peptides. (Adapted from FBrf0224587 and FBrf0238555.)
TNFalpha-EIGER SIGNALING PATHWAY CORE COMPONENTS -
The Tumor Necrosis Factor α (TNFα) signaling pathway is activated by Eiger (egr) binding to a member of the TNF receptor superfamily. The signal is primarily transduced via the Jun N-terminal kinase (JNK) cascade, leading to cell death. (Adapted from FBrf0225608.)
Protein Function (UniProtKB)
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.
(UniProt, Q9V3Q6)
Summary (Interactive Fly)

is a MAP kinase kinase kinase required for morphogenetic changes that take place during the fusion of the epithelial wing disc cell layers (thoracic closure), acting in the context of JNK signaling - required for Relish cleavage and antibacterial immunity - functions downstream of imd, Fadd and Diap2 and upstream of the IKK complex in the Imd pathway

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Testis-specificity index

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).

        Tak1 regulates autophagic cell death.

        dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

        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.

        Tak1 appears not to be strictly required for dorsal closure during embryogenesis. Tak1 is involved in ommatidial planar polarity signalling in the eye and thorax closure.

        Tak1 has a role in activation of Rel/NF-κB-mediated host defence reactions.

        Tak1 functions as a MAPKKK in the JNK signalling pathway and participates in such diverse roles as control of cell shape and regulation of apoptosis.

        The JNK signalling pathway is specifically activated by Tak1 signalling.

        Ectopic expression of Tak1 in the eye leads to a small eye phenotype due to ectopically induced apoptosis.
