CMG2 is a cell surface protein that binds to collagen VI and helps maintain the extracellular matrix, the structural network supporting tissues throughout the body. The research focuses on how cells regulate CMG2 through precise protein modifications that determine whether it functions properly at the cell surface or is degraded prematurely. Understanding CMG2's regulation is particularly significant because this protein is also exploited by anthrax toxin to enter and damage cells.
Why it matters
This research could lead to new therapeutic strategies for blocking anthrax infection by disrupting the mechanism that allows the toxin to enter cells via CMG2. Understanding the molecular switches that control CMG2 positioning and function may also have broader implications for treating diseases related to extracellular matrix dysfunction.
Every cell carefully builds and positions thousands of proteins that allow it to sense and respond to its surroundings. Even small changes to these proteins often determine whether they work properly or are destroyed before they ever reach the cell surface. One such protein is CMG2. By binding collagen VI, it helps maintain the extracellular matrix, the network of molecules that supports tissues throughout the body.
