Structure of Porins01:21

Structure of Porins

3.0K
Mitochondria, chloroplasts, and gram-negative bacteria have transmembrane, beta-barrel proteins called porins to mediate the free diffusion of ions and metabolites across the membrane. Mitochondrial porin precursors contain conserved amino acid sequences called beta signals at their C-terminal. Beta signals have a  motif of PoXGXXHyXHy (Po-Polar, X-Any amino acid, G-Glycine, Hy-LargeHydrophobic), which are crucial for precursor recognition to initiate precursor assembly. Beta-barrel...

Microvilli00:55

Microvilli

5.9K
Microvilli are tiny finger-like projections found on the surface of certain cells. Their purpose is to increase the surface area of the cell's apical surface, resulting in more effective absorption or secretion of substances.
These microvilli are predominantly present in cells lining the small intestine, kidney tubules, and certain cells in the respiratory and reproductive systems. By significantly expanding the surface area of the cell membrane, microvilli enhance the cell's capacity...

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

2.3K
Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Porin Insertion in the Outer Mitochondrial Membrane01:12

Porin Insertion in the Outer Mitochondrial Membrane

3.0K
Porins are beta-barrel proteins translocated to the mitochondrial outer membrane through the TOM complex into the intermembrane space. Porin precursors bind TIM chaperones within the intermembrane space and are guided to the Sorting and Assembly Machinery complex or SAM complex on the outer mitochondrial membrane.
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...

The Inner Mitochondrial Membrane01:28

The Inner Mitochondrial Membrane

3.3K
The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria.  In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...

Mechanism of Filopodia Formation01:39

Mechanism of Filopodia Formation

2.3K
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

Area of Science:

  • Parasitology
  • Cell Biology
  • Molecular Biology

Background:

  • The micropore is an essential structure for nutrient acquisition in apicomplexan parasites, including Plasmodium falciparum and Toxoplasma gondii.
  • Variations in micropore structure between P. falciparum and T. gondii raise questions about a universal apicomplexan micropore model and the applicability of the Plasmodium formation process to other species.

Purpose of the Study:

  • To investigate the structural diversity of apicomplexan micropores.
  • To determine if the Plasmodium micropore formation model is applicable to other apicomplexans.
  • To propose a novel model for micropore formation in T. gondii.

Main Methods:

  • Literature analysis of apicomplexan micropore structures.
  • Examination of the Kelch 13 (K13) protein interactome in T. gondii.
  • Analysis of gene depletion phenotypes in the T. gondii micropore.

Main Results:

  • Toxoplasma gondii likely possesses a more representative micropore structure compared to Plasmodium species.
  • The study identified key insights into the Kelch 13 (K13) protein interactome and gene depletion phenotypes relevant to T. gondii micropore formation.

Conclusions:

  • The findings suggest that T. gondii may offer a more generalizable model for apicomplexan micropore structure.
  • A new model for micropore formation in T. gondii is proposed, enhancing understanding of micropore protein function in apicomplexans.
