basic FUNCTION
| transporting the glycoproteins via a series of membrane vesicles and tubules to an acidic-sorting organelle where the receptor and ligand dissociates |
|
mediating the endocytosis of plasma glycoproteins to which the terminal sialic acid residue on their complex carbohydrate moieties has been removed |
|
is a novel important factor that responds to endogenous lectins in the tumor microenvironment to promote cancer metastasis by activating the EGFR-ERK pathway through interactions with counter-receptors on cancer cells  |
