Summary
Scientists developed a light-inducible tethering system to control organelle contacts in live cells. This tool precisely manipulates endoplasmic reticulum-mitochondria connections, aiding functional studies.
Area of Science:
- Cell Biology
- Molecular Biology
- Biophysics
Background:
- Organelle interfaces are crucial for cellular functions but difficult to study due to limited spatiotemporal control.
- Existing methods lack the precision to manipulate organelle contact formation in live cells.
Discussion:
- A novel genetically encoded light-inducible tethering (LIT) system was developed using the iLID system.
- This system allows precise, light-controlled induction of contacts between the endoplasmic reticulum (ER) and mitochondria.
- The LIT system demonstrates high spatiotemporal control in various cell types, including primary neurons.
Key Insights:
- The iLID-based LIT system provides unprecedented control over ER-mitochondria tethering.
- This technology enables researchers to investigate the functional roles of organelle contacts with high precision.
- The system's applicability in primary neurons opens new avenues for neuroscience research.
Outlook:
- Facilitates detailed functional studies of ER-mitochondria contacts in diverse biological contexts.
- Potential applications in studying other organelle interactions and cellular processes.
- Enables the development of new tools for optogenetic control of intracellular dynamics.

01:39Endoplasmic Reticulum
111.5K
The Endoplasmic Reticulum (ER) in eukaryotic cells is a substantial network of interconnected membranes with diverse functions, from calcium storage to biomolecule synthesis. A primary component of the endomembrane system, the ER manufactures phospholipids critical for membrane function throughout the cell. Additionally, the two distinct regions of the ER specialize in the manufacture of specific lipids and proteins.

01:45Tail-anchoring of Proteins in the ER Membrane
3.9K
Tail-anchored, or TA, proteins are estimated to make up to 3-5% of membrane proteins found in the eukaryotic cell. Such proteins have a single transmembrane domain located approximately 30 amino acid residues upstream from the C-terminal end. As a result, the signal recognition particle (SRP) cannot guide a TA protein to the ER membrane for cotranslational insertion. Hence, they are integrated into the ER membrane post-translationally using their C-terminal end as the anchor. TA proteins...

01:34Directing Proteins to the Rough Endoplasmic Reticulum
18.0K
The organelle-specific signaling sequences direct proteins synthesized in the cytosol to their final destination like ER, mitochondria, peroxisomes, etc. Some of the proteins directed to ER are then trafficked via vesicles to other organelles within the cell or the extracellular environment through the Golgi complex. For example, the rough ER synthesizes soluble proteins for transportation to the lysosomes or secretion out of the cell. It can also synthesize transmembrane proteins that can...

01:19Translocation of Proteins into the Mitochondria
13.5K
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

01:27Post-translational Translocation of Proteins to the RER
7.8K
A sizable fraction of proteins destined for ER are first synthesized in the cell cytosol and then transported across the ER membrane–a process called post-translational translocation. Similar to cotranslationally translocated proteins, these proteins also use the Sec translocon complex to enter the ER lumen.
Targeting proteins to the ER
Hsp40 and Hsp70 chaperone molecules bind the translated proteins in the cytosol to prevent their folding. The chaperone binding helps to keep the signal...

01:32Export of Misfolded Proteins out of the ER
5.3K
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...
