Paucimannose N-glycans in Caenorhabditis elegans and Drosophila melanogaster.
There is a rich diversity of paucimannose N-glycans in worms and flies, and these may play a role in the survival of these organisms. Although paucimannose N-glycans are not expressed in vertebrates, complex N-glycans may take over some of the functions of paucimannose N-glycans. Identification of the target proteins of beta-1,2-N-acetylglucosaminyltransferase I (GnTI) in worms and flies and elucidation of their functions may thus lead to a better understanding of the role of GnTI-dependent glycoproteins in the survival/longevity of both invertebrates and vertebrates.
