Insights

Eimeria tenella rhomboid 3 (EtROM3) protease cleaves the EtMIC4 surface protein during parasite invasion. This study confirms EtROM3

Area of Science:

  • Parasitology
  • Molecular Biology
  • Cell Biology

Background:

  • Apicomplexan parasite invasion involves shedding surface adhesins.
  • Rhomboid proteases mediate this shedding via intramembrane proteolysis.
  • The specific role of E. tenella rhomboid 3 (EtROM3) remains unclear.

Purpose of the Study:

  • To investigate the interactions between EtROM3 and microneme (MIC) proteins.
  • To elucidate the function of EtROM3 in Eimeria tenella.

Main Methods:

  • Yeast two-hybrid technique to analyze protein interactions.
  • Co-immunoprecipitation assays to confirm interactions.
  • Analysis of protein cleavage patterns.

Main Results:

  • EtROM3 was found to interact with the EtMIC4 protein.
  • Confirmation of EtROM3 and EtMIC4 interaction via immunoprecipitation.
  • Evidence suggests EtROM3 is an active protease that cleaves EtMIC4.

Conclusions:

  • EtROM3 plays a role in the invasion process of Eimeria tenella.
  • EtROM3 is involved in the proteolytic cleavage of EtMIC4.
  • Understanding EtROM3 function could reveal new targets for antiparasitic strategies.

Insertion of Multi-pass Transmembrane Proteins in the RER01:29

Insertion of Multi-pass Transmembrane Proteins in the RER

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...

Insertion of Single-pass Transmembrane Proteins in the RER

Integral membrane proteins are proteins adhered to the lipid bilayer of a cell organelle or membrane. They can be of two types: transmembrane integral proteins that span the lipid bilayer and monotopic proteins that are attached to either side of the membrane but do not pass through it.
Integral transmembrane proteins possess transmembrane and extra membrane domains. The transmembrane domains are primarily made of 20-25 hydrophobic amino acids arranged in a helical secondary confirmation. These...

Protein Modifications in the RER01:26

Protein Modifications in the RER

Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal...

The Early Endosome: Endocytosis of Transferrin01:28

The Early Endosome: Endocytosis of Transferrin

Essential proteins such as insulin or low-density lipoprotein (LDL) and micronutrients such as iron enter a eukaryotic cell through receptor-mediated endocytosis. Subsequently, the early endosomes fuse with the vesicles containing such receptor-ligand complexes and play a vital role in sorting the incoming ligands and receptors. While the ligands are either degraded inside the vesicle or released into the cytosol, their receptors are returned to the plasma membrane for further rounds of...
