Mediates the entry of L.monocytogenes into host intestinal epithelial cells, transformation with inlA alone allows L.innocua (a non-invasive species) to be taken up by host cells. Binds to human receptor cadherin-1 (E-cadherin, CDH1), the chicken homolog of cadherin-1 but not cadherin-2 function as receptors. Mouse cadherin-1 is not a receptor, however mutating a single surface-exposed residue (Glu-172 to Pro in mouse) allows cadherin-1 to act as a receptor for InlA.
