Summary
Malaria gametocytes, crucial for transmission, remodel host cells. This study maps their membrane protein complexes, identifying new targets for malaria eradication strategies.
Area of Science:
- Malariology
- Proteomics
- Structural Biology
Background:
- Malaria parasites (Plasmodium) form gametocytes, essential for mosquito transmission.
- Gametocytes remodel host erythrocytes via exported proteins, but their proteome is poorly understood.
- Gametocytes are key targets for transmission-blocking interventions against malaria.
Purpose of the Study:
- To investigate the gametocyte-specific membrane proteome and protein interactions.
- To identify novel host-pathogen and pathogen-pathogen protein complexes in gametocytes.
- To provide a molecular resource for developing transmission-blocking malaria interventions.
Main Methods:
- Crosslinking mass spectrometry to map protein proximities in the gametocyte membrane.
- Co-fractionation mass spectrometry to validate protein associations.
- AlphaFold and AF3x modeling using crosslinking data as restraints.
Main Results:
- Identified residue-level protein proximities within the gametocyte membrane proteome.
- Prioritized known and novel membrane-associated protein complexes.
- Integrated multiple data types to map complexes across parasite and host cell compartments.
Conclusions:
- Advanced molecular understanding of malaria gametocyte biology.
- Characterized the gametocyte membrane proteome and its complexes.
- Provided a foundation for future research on transmission-blocking strategies for malaria eradication.

Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

31.6K
Plasma membranes have integral transmembrane proteins involved in facilitated transport. These proteins are collectively referred to as transport proteins, and they function as either channels for the material or as carriers themselves. Channel proteins have hydrophilic domains exposed to the intracellular and extracellular fluids and a hydrophilic channel through their core that provides a hydrated opening for solutes to pass through the membrane layers. Passage through the channel allows...

The cell membrane, or plasma membrane, is an ever-changing landscape. It is described as a fluid mosaic where various macromolecules are embedded in the phospholipid bilayer. Among the macromolecules are proteins. The protein content varies across cell types. For example, mitochondrial inner membranes contain ~76% protein content, while myelin contains ~18% protein content. Individual cells contain many types of membrane proteins—red blood cells contain over 50—and different cell...

00:59Mechanisms of Membrane Domain Formation
4.4K
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
Another mechanism for membrane domain formation involves membrane proteins interacting with...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
