Cadherins are transmembrane proteins that contain calcium-binding domains, termed 'cadherin repeats' in their extracellular regions. As the major constituents of adherens junctions, cadherins of adjacent cells mediate intercellular adhesion by interacting with each other, and by associating with specialized protein complexes linked to the actin cytoskeleton through their intracellular regions.

    Epithelial cells form energetically costly cell–cell adhesions in response to mechanical forces. How cells obtain their energy during this event is unclear. Activity of a key regulator of cell metabolism, the AMP-activated protein kinase (AMPK), is now shown to be mechanoresponsive, and thus can bridge adhesion mechanotransduction and energy homeostasis.

    Tumours are highly complex and contain multiple cell types. Cancer-associated fibroblasts are now shown to have a critical role in directly leading cancer cell invasion. This intercellular interaction relies on a mechanically active cadherin-based junction, and CAF-led invasion is demonstrated to require E-cadherin in the cancer cell.

    Cadherin adhesion complexes have recently emerged as sensors of tissue tension that regulate key developmental processes. Super-resolution microscopy experiments now unravel the spatial organization of the interface between cadherins and the actin cytoskeleton and reveal how vinculin, a central component in cadherin mechanotransduction, is regulated by mechanical and biochemical signals.

    Many cell types in our body move in a collective manner, which requires individual cells to align their movements relative to that of their neighbours. A mechanism is now described in which cadherin-rich protrusions are extended from leading migrating cells and engulfed by follower cells to guide collective migration.
