Fascinating internal workings of our bodies.
The image shows an internal, cytoplasmic perspective, highlighting the protein complex that connects the cytoskeleton to the structures responsible for cell-cell adhesion.
Cadherin (not really visible, because most of it is in the extracellular space) is the transmembrane protein that links to the Actin cytoskeleton through the complex of Catenin and Vinculin, collectively forming the essential Adherens Junctions for strong cell-cell adhesion.
Actinin cross-links the Actin filaments.
