Summary
The plant receptor kinase BAK1/SERK3 partners with other receptors to regulate brassinosteroid signaling and immunity. This review explores BAK1
Area of Science:
- Plant molecular biology
- Plant signaling pathways
- Receptor kinase function
Background:
- The plant receptor kinase BAK1/SERK3 interacts with ligand-binding leucine-rich repeat receptor kinases.
- BAK1 is a known partner of the brassinosteroid receptor BRI1 and the immune receptor FLS2.
- BAK1 positively regulates BRI1 function through physical interaction and transphosphorylation.
Purpose of the Study:
- To summarize the known functions of BAK1/SERK3.
- To discuss the integration of BAK1's diverse roles.
- To explore the formation of receptor complexes and specificity determination.
Main Methods:
- Literature review of studies on BAK1/SERK3.
- Analysis of BAK1's role in brassinosteroid signaling, light responses, cell death, and plant immunity.
- Discussion of molecular mechanisms underlying BAK1 function.
Main Results:
- BAK1/SERK3 participates in multiple plant processes beyond brassinosteroid signaling.
- BAK1 is implicated in light responses, cell death, and innate immunity.
- BAK1 acts as a crucial signaling hub integrating various stimuli.
Conclusions:
- BAK1/SERK3 is a versatile receptor kinase with a broad functional repertoire.
- Understanding BAK1's integration mechanisms is key to deciphering plant signaling.
- Further research is needed to fully elucidate receptor complex formation and specificity.

01:07MAPK Signaling Cascades
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
01:22Amplifying Signals via Enzymatic Cascade
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
01:22PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
01:26Receptor Tyrosine Kinases
Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...
01:19Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
