OBJECTIVE
Comprehensive proteomic profiling of the human adipocyte secretome identified dipeptidyl peptidase 4 (DPP4) as a novel adipokine. This study assessed the functional implications of the… (More)
Fibulins are a family of five extracellular matrix proteins characterized by tandem arrays of epidermal growth factor-like domains and a C-terminal fibulin-type module. They are widely distributed… (More)
While only about ten percent of the databank entries are defined as glycoproteins, it has been estimated recently that more than half of all proteins are glycoproteins. Mucin-type O-glycosylation is… (More)
Since there is no consensus sequence directing the initial GalNAc incorporation into mucin peptides, O-glycosylation sites are not reliably predictable. We have developed a mass spectrometric… (More)
In contrast to protein antigens, processing of glycoproteins by dendritic cells (DCs) for presentation to T cells has not been well studied. We developed mouse T cell hybridomas to study processing… (More)
Human bone sialoprotein (BSP) comprises 15% of the total noncollagenous proteins in bone and is thought to be involved in bone mineralization and remodeling. Recent data suggest a role for BSP in… (More)
We present evidence that site-specific O-glycosylation by recombinant polypeptide N-acetylgalactosaminyltransferases rGalNAc-T2 and -T4 is controlled by the primary sequence context, as well as by… (More)
The expression of MUC1 and MUC2 mucin peptide core antigens in gastric carcinomas was studied by immunohistochemistry to determine correlations with TNM stage and histo-pathological classifications… (More)
O-Linked oligosaccharides were isolated from human skim milk mucins and from mucin-derived glycopeptides by reductive beta-elimination. The released alditols were fractionated by DEAE-Sephadex… (More)
This study shows for the first time that the tandemly repeated icosapeptide of human MUC1 underlies a genetic sequence polymorphism at three positions (underlined): PDTRPAPGSTAPPAHGVTSA. The… (More)
