1 Originally, sialoadhesin was characterized as a lymphocyte adhesion molecule, though recently its involvement in internalization of sialic acid carrying pathogens was shown, suggesting that sialoadhesin is an endocytic receptor. N-Acetylneuraminic Acid sialic acid binding Ig like lectin 1 Homo sapiens

3 Together, these data expand sialoadhesin functionality and show that it can function as an endocytic receptor, a feature that cannot only be misused by sialic acid carrying pathogens, but that may also be used for specific targeting of toxins or antigens to sialoadhesin-expressing macrophages. N-Acetylneuraminic Acid sialic acid binding Ig like lectin 1 Homo sapiens
