Medical Definition of Invasins
1. Proteins produced by bacterial cells that promote bacterial penetration into mammalian cells. The invasin produced by Yersinia pseudotuberculosis seems to bind to the fibronectin receptor (_5 _1 integrin) at a site close to the fibronectin binding site, though the invasin does not have an RGD sequence.
