Integrins are cell surface receptors for extracellular matrix proteins and, as such, regulate adhesive cell–matrix interactions. New findings indicate that the β4 integrin subunit can also function as a signalling effector for the activated receptor tyrosine kinase Met and enhance invasive growth independent of its adhesive role.
