The research report should be a detailed narrative explaining the function, biological processes, and localization of the gene product. Citations should be given for all claims.
You should prioritize authoritative reviews and primary scientific literature when conducting research. You can supplement
this with annotations you find in gene/protein databases, but these can be outdated or inaccurate.
We are specifically interested in the primary function of the gene - for enzymes, what reaction is catalyzed, and what is the substrate specificity? For transporters, what is the substrate? For structural proteins or adapters, what is the broader structural role? For signaling molecules, what is the role in the pathway.
We are interested in where in or outside the cell the gene product carries out its function.
We are also interested in the signaling or biochemical pathways in which the gene functions. We are less interested in broad pleiotropic effects, except where these elucidate the precise role.
Include evidence where possible. We are interested in both experimental evidence as well as inference from structure, evolution, or bioinformatic analysis. Precise studies should be prioritized over high-throughput, where available.
MAPKKK5 is the Arabidopsis thaliana protein encoded by At5g66850, corresponding to the supplied UniProt accession Q9C5H5. It is a MEKK-subfamily mitogen-activated protein kinase kinase kinase (MAP3K) with a central protein-kinase domain and regulatory N- and C-terminal regions. It must not be confused with its downstream substrate MKK5, its related kinase MAPKKK3, or YODA/MAPKKK4. The locus, organism, family and domain organization are explicitly corroborated in a primary study. [UniProt: https://www.uniprot.org/uniprotkb/Q9C5H5/entry; Yamada et al., EMBO Journal, September 2016, https://doi.org/10.15252/embj.201694248.] (yamada2016thearabidopsiscerk1‐associated pages 2-3)
Its best-established molecular function is ATP-dependent phosphorylation of the MAPK kinases MKK4 and MKK5, placing it upstream of the MKK4/MKK5–MPK3/MPK6 signaling module. In purified-protein assays, the MAPKKK5 kinase domain phosphorylated kinase-inactive MKK4 and MKK5. Substituting the paired activation-loop residues T224/S230 in MKK4 or T215/S221 in MKK5 with alanine greatly reduced phosphorylation. MKK5 received a stronger signal than MKK4 under those assay conditions; MKK1 was not detectably phosphorylated, and MKK2 received only weak phosphorylation that did not depend on its corresponding activation-loop motif. These findings establish direct substrates and qualitative selectivity, not in-vivo kinetic constants or an exhaustive substrate list. [Yamada et al., 2016, https://doi.org/10.15252/embj.201694248; Figure 8.] (yamada2016thearabidopsiscerk1‐associated pages 10-12, yamada2016thearabidopsiscerk1‐associated media b35e07cb)
The following evidence map distinguishes phosphorylation by MAPKKK5 from regulatory phosphorylation of MAPKKK5.
| Biological step | Observed direct evidence | Qualification |
|---|---|---|
| Catalytic output to MAPKKs | Purified MAPKKK5 kinase domain transferred phosphate from ATP to kinase-inactive MKK4 and MKK5. Double-alanine substitutions in their activation loops—MKK4 T224A/S230A and MKK5 T215A/S221A—largely abolished phosphorylation; MKK5 was phosphorylated more strongly than MKK4 under the assay conditions. Yamada et al. (2016), DOI: 10.15252/embj.201694248. (yamada2016thearabidopsiscerk1‐associated pages 10-12, yamada2016thearabidopsiscerk1‐associated media b35e07cb) | Strongest direct evidence for enzymatic substrate specificity. MKK1 was not phosphorylated; MKK2 showed only weak phosphorylation not dependent on its canonical activation-loop motif. In-vitro preference does not establish quantitative kinetics or exclusive substrates in vivo. (yamada2016thearabidopsiscerk1‐associated pages 10-12) |
| CERK1–PBL27 input | PBL27 phosphorylated six MAPKKK5 C-terminal residues—S617, S622, S658, S660, T677 and S685—in vitro; S622A caused the largest individual reduction. CERK1 kinase activity enhanced PBL27-mediated phosphorylation but CERK1 did not directly phosphorylate the tested MAPKKK5 tail. Yamada et al. (2016), DOI: 10.15252/embj.201694248. (yamada2016thearabidopsiscerk1‐associated pages 9-10, yamada2016thearabidopsiscerk1‐associated pages 6-8, yamada2016thearabidopsiscerk1‐associated pages 8-9) | The six-site alanine variant only partly restored chitin-induced MAPK activation and callose deposition. Bi et al. (2018) could not reproduce a PBL27 requirement: phosphorylation was normal in pbl27 and instead depended on RLCK VII-4 proteins. Thus, PBL27’s essential in-vivo role remains disputed. DOI: 10.1105/tpc.17.00981. (yamada2016thearabidopsiscerk1‐associated pages 8-9, bi2018receptorlikecytoplasmickinases pages 8-11) |
| BSK1 input | BSK1 physically associated with the MAPKKK5 kinase domain and directly phosphorylated the MAPKKK5 N-terminal region, principally at S289. S289A largely eliminated phosphorylation, failed to restore bacterial and powdery-mildew resistance, whereas phosphomimetic S289D restored resistance. Yan et al. (2018), DOI: 10.1104/pp.17.01757. (yan2018brassinosteroidsignalingkinase1phosphorylates pages 7-11) | S289 phosphorylation was required for tested immune functions but not for MAPKKK5-induced cell death in transiently transformed Nicotiana benthamiana. This establishes regulatory phosphorylation of MAPKKK5, not BSK1 as its downstream substrate. (yan2018brassinosteroidsignalingkinase1phosphorylates pages 7-11) |
| RLCK VII-4/PBL19 input | Chitin induced MAPKKK5 S599 phosphorylation. In the presence of the CERK1 kinase domain, PBL19 phosphorylated the MAPKKK5 tail at S599 in vitro; RLCK VII-4 sextuple mutants retained only about 25% of normal chitin-induced MAPKKK5 phosphorylation. S599A failed to restore MPK3/6 activation, whereas wild-type MAPKKK5 and S599D produced about 3.5-fold the empty-vector response. Bi et al. (2018), DOI: 10.1105/tpc.17.00981. (bi2018receptorlikecytoplasmickinases pages 35-41, bi2018receptorlikecytoplasmickinases pages 8-11) | S599D did not activate MPK3/6 without elicitation, showing that S599 phosphorylation is necessary but insufficient. Functional tests used MAPKKK5 transgenes in a mapkkk3 mapkkk5 background and therefore account for MAPKKK3 redundancy. (bi2018receptorlikecytoplasmickinases pages 11-15, bi2018receptorlikecytoplasmickinases pages 8-11) |
| MPK6 positive feedback | Activated MPK6 directly phosphorylated MAPKKK5 at S682 and S692 in vitro. Phospho-dead substitutions weakened chitin/flg22 signaling, FRK1 induction and pathogen resistance; phosphomimetic substitutions enhanced or prolonged MPK3/6 activation, supporting a positive-feedback loop. Bi et al. (2018), DOI: 10.1105/tpc.17.00981. (bi2018receptorlikecytoplasmickinases pages 11-15, bi2018receptorlikecytoplasmickinases pages 41-45) | MAPKKK5 is the substrate in this feedback reaction; MPK3/6 remain downstream MAPKs rather than direct primary substrates of MAPKKK5. Effects were evaluated mainly through complementation of mapkkk3 mapkkk5. (bi2018receptorlikecytoplasmickinases pages 11-15, bi2018receptorlikecytoplasmickinases pages 21-25) |
| Subcellular execution | Fractionation detected MAPKKK5 in soluble/cytosolic and microsomal/plasma-membrane fractions. Co-IP/BiFC placed its PBL27 complex at the plasma membrane, while BiFC localized interactions with MKK4 and MKK5 mainly to the cytosol. Yamada et al. (2016), DOI: 10.15252/embj.201694248. (yamada2016thearabidopsiscerk1‐associated pages 10-12, yamada2016thearabidopsiscerk1‐associated pages 4-5, yamada2016thearabidopsiscerk1‐associated pages 12-13) | The evidence supports dynamic compartmental signaling rather than an exclusively membrane-bound or exclusively cytosolic protein. Chitin induced dissociation of the PBL27–MAPKKK5 complex. (yamada2016thearabidopsiscerk1‐associated pages 6-8, yamada2016thearabidopsiscerk1‐associated pages 1-2) |
| Genetics and redundancy | Yamada et al. reported strong chitin defects in single mapkkk5 mutants, whereas Bi et al. found normal chitin responses and only slight flg22 reduction in single mutants but marked loss of flg22-, chitin-, elf18- and Pep2-triggered MPK3/6 activation in mapkkk3 mapkkk5 double mutants. DOI: 10.15252/embj.201694248; 10.1105/tpc.17.00981. (yamada2016thearabidopsiscerk1‐associated pages 2-3, bi2018receptorlikecytoplasmickinases pages 35-41, bi2018receptorlikecytoplasmickinases pages 4-8) | The reproducible higher-order-mutant evidence indicates substantial MAPKKK3/MAPKKK5 redundancy; conclusions from single mutants are laboratory- and assay-dependent. Yamada et al. additionally reported enhanced flg22-triggered MAPK activation, which Bi et al. did not reproduce. (bi2018receptorlikecytoplasmickinases pages 4-8, yamada2016thearabidopsiscerk1‐associated pages 12-13) |
| Development with YDA/MAPKKK4 | mapkkk5 yda double-knockout and mapkkk3 mapkkk5 yda triple-knockout combinations could not be recovered because embryogenesis failed. Weak CRISPR yda-del alleles in the mapkkk3 mapkkk5 background further reduced PAMP-triggered MPK3/6 activation and increased pathogen susceptibility. Liu et al. (2022), DOI: 10.1111/jipb.13309. (liu2022overlappingfunctionsof pages 7-8, liu2022overlappingfunctionsof pages 1-2) | These are overlapping genetic functions upstream of MKK4/MKK5–MPK3/MPK6, not proof that MAPKKK5 alone controls embryogenesis. MAPKKK5 made the stronger reproductive contribution relative to MAPKKK3 in the YDA-deficient background. (liu2022overlappingfunctionsof pages 7-8, liu2022overlappingfunctionsof pages 1-2) |

Chitin-triggered immunity. The fungal chitin receptor complex LYK5–CERK1 provides an experimentally studied route into MAPKKK5-dependent signaling. Yamada and colleagues found that receptor-associated PBL27 interacts with MAPKKK5 at the plasma membrane, phosphorylates its C-terminal region in vitro more strongly when PBL27 is activated by CERK1, and dissociates from MAPKKK5 following chitin perception. Mass spectrometry identified six PBL27-phosphorylated MAPKKK5 residues—S617, S622, S658, S660, T677 and S685—with S622 particularly influential in their assay. A six-site alanine variant did not fully restore chitin-induced MAPK activation or callose deposition to a mapkkk5 mutant. CERK1 itself did not directly phosphorylate the tested MAPKKK5 C-terminal fragment. [Yamada et al., 2016, https://doi.org/10.15252/embj.201694248.] (yamada2016thearabidopsiscerk1‐associated pages 1-2, yamada2016thearabidopsiscerk1‐associated pages 6-8, yamada2016thearabidopsiscerk1‐associated pages 8-9)
A separate study identified an RLCK VII-4-dependent input, including the kinase PBL19. In the presence of the CERK1 kinase domain, PBL19 phosphorylated MAPKKK5 S599 in vitro; chitin induced S599 phosphorylation in plants. Introducing wild-type MAPKKK5 or S599D into a mapkkk3 mapkkk5 background yielded approximately 3.5-fold the chitin-induced MPK3/MPK6 activation measured in the empty-vector control, whereas S599A did not rescue it. S599D did not activate MPK3/MPK6 without elicitation: that modification is important but insufficient on its own. S599-dependent signaling also supported defense-gene induction and resistance in the tested bacterial and fungal challenges. [Bi et al., The Plant Cell, June 2018, https://doi.org/10.1105/tpc.17.00981.] (bi2018receptorlikecytoplasmickinases pages 11-15, bi2018receptorlikecytoplasmickinases pages 8-11)
Feedback and additional regulation. Activated MPK6 directly phosphorylates MAPKKK5 at S682 and S692, establishing feedback from a downstream MAPK to this MAP3K; MPK3/MPK6 are not thereby demonstrated to be MAPKKK5’s direct catalytic substrates. Altering these sites changed the duration or strength of elicitor-induced MPK3/MPK6 signaling, defense-gene expression and pathogen resistance. Another upstream kinase, BSK1, interacts with the MAPKKK5 kinase domain but phosphorylates its N-terminal S289. S289A substantially reduced phosphorylation and failed to restore resistance to the tested Pseudomonas syringae strains and powdery mildew, whereas S289D restored resistance; neither substitution abolished cell death elicited by transient MAPKKK5 expression in Nicotiana benthamiana. [Bi et al., 2018, https://doi.org/10.1105/tpc.17.00981; Yan et al., Plant Physiology, February 2018, https://doi.org/10.1104/pp.17.01757.] (bi2018receptorlikecytoplasmickinases pages 11-15, yan2018brassinosteroidsignalingkinase1phosphorylates pages 7-11)
Genetic outcomes. A 2016 study found that two independent single-gene mapkkk5 mutants had strongly reduced chitin-triggered MPK3/MPK4/MPK6 activation; native-promoter MAPKKK5 expression rescued signaling. It also found reduced chitin-induced callose and greater susceptibility to Alternaria brassicicola, while the measured chitin-triggered reactive-oxygen burst was unchanged. In that study, 656 expression patterns differed between mutant and wild type among 12,992 genes significantly responsive to chitin in wild type; these are transcriptional associations, not a count of direct MAPKKK5 targets. [Yamada et al., 2016, https://doi.org/10.15252/embj.201694248.] (yamada2016thearabidopsiscerk1‐associated pages 2-3, yamada2016thearabidopsiscerk1‐associated pages 3-4)
The distinction between single-gene and redundant functions is essential. Bi and colleagues found near-normal chitin responses in single mapkkk5 mutants but substantially diminished MPK3/MPK6 activation after chitin, flg22, elf18 or Pep2 treatment in mapkkk3 mapkkk5 double mutants. The double mutants also showed impaired FRK1 induction and greater susceptibility to P. syringae and Botrytis cinerea. Their S599 and S682/S692 complementation experiments therefore demonstrate what MAPKKK5 can contribute when MAPKKK3 is absent, rather than proving that MAPKKK5 acts alone in intact plants. [Bi et al., 2018, https://doi.org/10.1105/tpc.17.00981.] (bi2018receptorlikecytoplasmickinases pages 35-41)
MAPKKK5 functions inside the cell, at a receptor-proximal plasma-membrane interface and in the cytosol, rather than as an extracellular enzyme. Fractionation of heterologously expressed protein detected soluble and membrane-associated pools. Co-immunoprecipitation and fluorescence-complementation assays placed its association with PBL27 at the plasma membrane, while interactions with MKK4/MKK5 were observed mainly in the cytosol of Arabidopsis protoplasts. Chitin-induced separation of the PBL27–MAPKKK5 complex is consistent with a transition between signaling partners; the experiments do not establish that every MAPKKK5 molecule physically translocates from membrane to cytosol. [Yamada et al., 2016, https://doi.org/10.15252/embj.201694248.] (yamada2016thearabidopsiscerk1‐associated pages 6-8, yamada2016thearabidopsiscerk1‐associated pages 4-5, yamada2016thearabidopsiscerk1‐associated pages 10-12)
A 2022 genetic analysis established overlap among MAPKKK5, MAPKKK3 and YODA/MAPKKK4 upstream of the MKK4/MKK5–MPK3/MPK6 module. Complete mapkkk5 yda double-mutant and mapkkk3 mapkkk5 yda triple-mutant combinations could not be recovered because embryogenesis failed; MAPKKK5 therefore contributes with YDA to reproductive development, but is not individually established as indispensable for embryogenesis. Weak CRISPR-generated yda alleles in the mapkkk3 mapkkk5 background further reduced pattern-induced MPK3/MPK6 activation and increased pathogen susceptibility compared with the double mutant. [Liu et al., Journal of Integrative Plant Biology, July 2022, https://doi.org/10.1111/jipb.13309.] (liu2022overlappingfunctionsof pages 7-8, liu2022overlappingfunctionsof pages 1-2)
A July 2026 Arabidopsis study broadened the cascade’s experimentally supported context to mechanical stimulation. Touch or wounding activated the combined MAPKKK3/YDA/MAPKKK5–MKK4/MKK5–MPK3/MPK6 module within 60 seconds, with approximately 800 early touch-responsive genes implicated in the overall response. In a two-week brushing experiment, rosette area fell by approximately 38% in wild type versus 20% in a mapkkk3 mapkkk5 yda weak-allele background and 28% in mkk4 mkk5. These are higher-order-genotype, not MAPKKK5-specific, measurements. [Tran et al., Nature Communications, July 2026, https://doi.org/10.1038/s41467-026-74994-x.] (tran2026asequentialmap pages 10-12, tran2026asequentialmap pages 1-2)
The practical implementation of these findings is presently mechanistic research in Arabidopsis: knockout, complementation and phosphosite variants identify immune-cascade nodes and experimentally test kinase connectivity. The cited work does not establish a deployed MAPKKK5-directed crop intervention; moreover, embryogenesis defects in combined kinase mutants caution against treating pathway enhancement or disruption as developmentally cost-free. [Bi et al., 2018, https://doi.org/10.1105/tpc.17.00981; Liu et al., 2022, https://doi.org/10.1111/jipb.13309.] (bi2018receptorlikecytoplasmickinases pages 35-41, liu2022overlappingfunctionsof pages 1-2)
The receptor-to-MAPKKK5 connection is not fully settled. Yamada et al. reported a required PBL27-dependent chitin route and strongly defective chitin signaling in single mapkkk5 mutants; they also observed enhanced flg22-triggered MAPK activation in those mutants. Bi et al. explicitly reported inability to reproduce the PBL27 requirement or those single-mutant outcomes: their pbl27 cells retained normal MAPKKK5 phosphorylation, whereas an RLCK VII-4 sextuple mutant retained only approximately 25% of normal chitin-induced MAPKKK5 phosphorylation; their single mapkkk5 mutants showed normal chitin responses and only slightly reduced flg22-induced MPK3/MPK6 activation. Distinct RLCK routes may exist, but these experiments do not establish a unified explanation of the discrepancy. The most secure functional annotation is therefore MAPKKK5-dependent phosphorylation of MKK4/MKK5 and a partly redundant role in inducible MAPK signaling, with the requirement for any one proposed upstream RLCK explicitly qualified. [Yamada et al., 2016, https://doi.org/10.15252/embj.201694248; Bi et al., 2018, https://doi.org/10.1105/tpc.17.00981.] (bi2018receptorlikecytoplasmickinases pages 4-8, yamada2016thearabidopsiscerk1‐associated pages 12-13, yamada2016thearabidopsiscerk1‐associated pages 10-12, bi2018receptorlikecytoplasmickinases pages 8-11)
Peer-reviewed 2023 and 2024 papers specifically addressing 14-3-3 regulation and MPK3-dependent phosphorylation of MAPKKK5 were identified in bibliographic search, but their primary full texts were not available for verification here; their detailed mechanistic claims have therefore not been incorporated as established findings. This limits coverage of those requested years, rather than warranting substitution of results from similarly named rice, soybean or mammalian proteins.
