Mechanisms in protein O-glycan biosynthesis and clinical and molecular aspects of protein O-glycan biosynthesis defects: a review.
BACKGROUND Genetic diseases that affect the biosynthesis of protein O-glycans are a rapidly growing group of disorders. Because this group of disorders does not have a collective name, it is difficult to get an overview of O-glycosylation in relation to human health and disease. Many patients with an unsolved defect in N-glycosylation are found to have an abnormal O-glycosylation as well. It is...
متن کاملApolipoprotein C-III isofocusing in the diagnosis of genetic defects in O-glycan biosynthesis.
BACKGROUND Defects in the biosynthesis of N-glycans may be found by isoelectric focusing (IEF) of plasma transferrin. No test is available to demonstrate O-glycan biosynthesis defects. METHODS We used isoforms of apolipoprotein C-III (apoC-III) as a marker for the biosynthesis of core 1 mucin type O-glycans. Plasma samples from patients with primary defects and secondary alterations in N-glyc...
متن کاملMammalian O-Mannosylation Pathway: Glycan Structures, Enzymes, and Protein Substrates
The mammalian O-mannosylation pathway for protein post-translational modification is intricately involved in modulating cell-matrix interactions in the musculature and nervous system. Defects in enzymes of this biosynthetic pathway are causative for multiple forms of congenital muscular dystophy. The application of advanced genetic and biochemical technologies has resulted in remarkable progres...
متن کاملTransferrin and apolipoprotein C-III isofocusing are complementary in the diagnosis of N- and O-glycan biosynthesis defects.
BACKGROUND Apolipoprotein C-III (apoC-III) isoelectric focusing (IEF) can be used to detect abnormalities in the biosynthesis of core 1 mucin-type O-glycans. METHODS We studied plasma samples from 55 patients with various primary defects in N- and/or O-glycosylation, 21 patients with secondary N-glycosylation defects, and 6 patients with possible glycosylation abnormalities. Furthermore, we a...
متن کاملNotable Aspects of Glycan-Protein Interactions
This mini review highlights several interesting aspects of glycan-mediated interactions that are common between cells, bacteria, and viruses. Glycans are ubiquitously found on all living cells, and in the extracellular milieu of multicellular organisms. They are known to mediate initial binding and recognition events of both immune cells and pathogens with their target cells or tissues. The hos...
