Summary
Protein-protein interactions (PPIs) are vital for plant cell communication. Phosphorylation-related proteins acting across organelles are key to this communication, offering new research avenues in plant science.
Area of Science:
- Plant molecular biology
- Proteomics
- Cellular signaling
Background:
- Protein-protein interactions (PPIs) are fundamental to cellular processes like signal transduction and apoptosis.
- Understanding PPIs aids in identifying protein complexes and functions.
- Arabidopsis thaliana proteome data enables cellular process modeling and experimental research.
Purpose of the Study:
- To analyze PPI networks in 10 major organelles of Arabidopsis thaliana.
- To investigate the role of PPIs in organelle communication.
- To explore the function of multilocation proteins, particularly phosphorylation-related ones, in inter-organelle communication.
Main Methods:
- Overview analysis of PPI networks in Arabidopsis thaliana organelles.
- Comparative analysis with rice (monocotyledonous crop).
- Proposed research strategy involving LOPIT technique, proteomics, and bioinformatics for multilocation proteins.
Main Results:
- PPIs play a significant role in organelle communication in Arabidopsis thaliana.
- Multilocation proteins, especially those involved in phosphorylation, act as crucial links in organelle communication.
- Similar findings were observed in rice, suggesting conserved mechanisms.
Conclusions:
- Phosphorylation-related multilocation proteins are central to organelle communication.
- This research provides novel insights into PPIs and proteomic research directions.
- Understanding these proteins offers a theoretical basis for plant stress responses and organelle communication development.

4.1K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

13.9K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

01:45Overview of Protein Sorting and Transport
14.9K
Eukaryotic cells have different membrane-bound organelles with distinct protein requirements. The process by which proteins are targeted to a specific organelle is called protein sorting.
Protein sorting can be of two types: signal-based sorting and vesicle-based trafficking. In signal-based sorting, specific amino acid sequences called sorting signals target proteins to the proper location inside the cell either via gated transport or by protein translocation. In gated transport, folded...

The translocon complex situated on the ER membrane is the main gateway for the protein secretory pathway. It facilitates the transport of nascent peptides into the ER lumen and their insertion into the ER membrane.
Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the...

01:30Assembly of Signaling Complexes
6.0K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

The rough ER membrane synthesizes, assembles, and embeds transmembrane proteins in diverse topologies. These proteins function as transporters or channels and can remain in the ER membrane or are sent to the Golgi complex, lysosome, and cell membrane.
The multipass transmembrane proteins are the type IV integral membrane proteins with multiple topogenic sequences determining their spatial arrangement in the ER membrane. Nearly all multipass proteins lack a cleavable signal sequence and use...
