N-linked oligosaccharides of vomeromodulin, a putative pheromone transporter in rat.
Vomeromodulin, a putative pheromone transporter of the rat vomeronasal organ, was isolated by lectin chromatography, purified, and subjected to a mass spectrometric (MS) system of glycan structural determination. Through a combination of exoglycosidase treatments and measurements by matrix-assisted laser desorption/ionization MS, the N-glycans of vomeromodulin were identified as mainly sialylated and fucosylated biantennary structures. The microheterogeneity of N-glycan structures was also due to the presence of galactose residues with different types of linkages.
