Fusion of Secretory Vesicles with the Plasma Membrane

Fusion of Secretory Vesicles with the Plasma Membrane

Proteins and neurotransmitters in secretory vesicles can be released from a cell upon vesicle docking, priming, and fusion with the plasma membrane. Vesicles are docked and primed in preparation for the quick exocytosis of their contents in response to a stimulus. The fusion process is mainly carried out by a SNAP Receptor or SNARE complex, consisting of synaptobrevin, syntaxin-1, and SNAP-25.
In 1993, Jim Rothman proposed that the antiparallel pairing of vesicular and transmembrane SNAREs, or...

Protein Complexes with Interchangeable Parts

Protein Complexes with Interchangeable Parts

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order to...

Pinching-off of Coated Vesicles

Pinching-off of Coated Vesicles

Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...

Condensins

Condensins

Condensins are large protein complexes that use ATP to fuel the assembly of chromosomes during mitosis. They transform the tangled, shapeless mass of post-interphase DNA into individualized chromosomes by compacting, organizing, and segregating chromosomal DNA.
The plant and animal cells contain two types of condensin complexes—condensin I and condensin II. Both complexes have five subunits: two SMC (Structural Maintenance of Chromosomes) subunits, a kleisin subunit, and two HEAT-repeat...

Background:

Complexins are key proteins involved in regulating neurotransmitter release at the synapse.
Previous studies on complexin knockout and perturbations have yielded conflicting results regarding their precise function in exocytosis.

Discussion:

The study investigates the intricate Ca(2+)-dependent interaction between complexin and synaptotagmin in triggering exocytosis.
It presents new data that adds complexity to the existing models of this critical molecular switch.

Key Insights:

New findings elucidate the detailed mechanism of the complexin-synaptotagmin switch in calcium-triggered neurotransmitter release.
The research challenges and refines current understandings of complexin's role in synaptic vesicle exocytosis.

Outlook:

The results may lead to a revised and potentially simpler model of complexin function in synaptic transmission.
Further research could explore alternative interpretations and their implications for neurological disorders involving neurotransmitter release defects.
