Summary
N-MYC DOWNREGULATED-LIKE (NDL) proteins in plants may help manage abiotic stress by stabilizing microtubules. Their interaction with G-protein signaling suggests a role in plant stress tolerance.
Area of Science:
- Plant Biology
- Molecular Biology
- Biochemistry
Background:
- N-MYC DOWNREGULATED-LIKE (NDL) proteins, part of the alpha/beta hydrolase superfamily, are implicated in G-protein signaling in Arabidopsis thaliana.
- In animals, NDL homologs (NDRG) are involved in stress responses, particularly hypoxia, and function as microtubule-associated proteins.
Purpose of the Study:
- To investigate the potential role of NDL proteins in plant microtubule organization and abiotic stress management.
- To explore the homology between plant NDL1 and animal NDRG for functional insights.
Main Methods:
- Analysis of NDL protein interactions within the G-protein interactome.
- Comparative analysis of NDL proteins with animal NDRG counterparts.
Main Results:
- NDL proteins were identified as interactors in the plant G-protein interactome, including associations with tubulin alpha-2 chain.
- Predicted interactions suggest NDL proteins may play a role in microtubule stabilization.
Conclusions:
- NDL proteins are hypothesized to be involved in microtubule organization during plant abiotic stress responses.
- NDL proteins represent potential targets for enhancing plant stress tolerance.

02:17Microtubule Instability
6.4K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

01:45Destabilization of Microtubules
3.9K
The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...

Bacteria have global regulatory systems that control several types of stress mechanisms. These include Pho regulon and the heat shock response, which are essential systems for environmental adaptation, such as nutrient limitation and proteotoxic stress. The Pho regulon and the heat shock response exemplify bacterial resilience, enabling rapid adaptation to fluctuating environmental conditions.Pho RegulonBacteria require phosphorus for essential cellular processes, including nucleic acid...

01:31Regulation of the Unfolded Protein Response
3.2K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

01:26Bacterial Protein Maturation
701
Bacterial protein maturation is a tightly regulated process that ensures newly synthesized polypeptides achieve correct functional conformations. This maturation involves a series of modifications, folding events, and quality control steps, often assisted by specialized chaperone proteins.N-Terminal ModificationsThe maturation of bacterial polypeptides begins cotranslationally as the polypeptide exits the ribosome. The first amino acid, N-formylmethionine (fMet), is typically modified at the...
