DESCRIPTION
Also known as INLA_LISMO, inlA. 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 (PubMed:1905979, PubMed:8601315, PubMed:10406800). Binds to human receptor cadherin-1 (E-cadherin, CDH1); the chicken homolog of cadherin-1 but not cadherin-2 function as receptors (PubMed:8601315). 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 (PubMed:10406800). Interacts with host (human) cadherin-1 (CDH1) (PubMed:12526809, PubMed:17540170, PubMed:17715295). The formation of the complex between inlA and cadherin-1 is calcium-dependent (PubMed:12526809). Mutagenesis studies show it is possible to increase the affinity of InlA for CDH1 by rational engineering of InlA residues (PubMed:17715295).
