Proteins following the secretory pathway acquire their proper tertiary and in certain cases also quaternary structures in the endoplasmic reticulum (ER). Incompletely folded species are retained in the ER and eventually degraded. One of the molecular mechanisms by which cells achieve this conformational sorting is based on monoglucosylated N-glycans ...

P-Glycoprotein: One Mechanism, Many Tasks and the Consequences for Pharmacotherapy of Cancers
P-glycoprotein or multidrug resistance protein (MDR1) is an adenosine triphosphate (ATP) binding cassette transporter (ABCB1) intensely investigated because it is an obstacle to successful pharmacotherapy of cancers.

Fucosylation and protein glycosylation create functional receptors for cholera toxin
Cholera toxin (CT) enters and intoxicates host cells after binding cell surface receptors using its B subunit (CTB). The ganglioside (glycolipid) GM1 is thought to be the sole CT receptor; however, the mechanism by which CTB binding to GM1 mediates ...

Crystal Structure of the Pre-fusion Nipah Virus Fusion Glycoprotein Reveals a Novel Hexamer-of-Trimers Assembly. [PDF]
Nipah virus (NiV) is a paramyxovirus that infects host cells through the coordinated efforts of two envelope glycoproteins. The G glycoprotein attaches to cell receptors, triggering the fusion (F) glycoprotein to execute membrane fusion.

To evaluate whether alterations in the multidrug-resistance (MDR)-1 gene correlate with intestinal MDR-1 expression and uptake of orally administered P-glycoprotein (PGP) substrates, we analyzed the MDR-1 sequence in 21 volunteers whose PGP expression ...

Glycoprotein Processing and Glycoprotein Processing Inhibitors [PDF]
Considerable evidence is now accumulating from both in vivo and in vitro studies that the oligosaccharide chains of the plant N-linked glycoproteins undergo modification or processing reactions after the oligosaccharide has been transferred from its lipid-linked oligosaccharide intermediate to the protein.

Functional Divergence of Glycoprotein Hormone Receptors [PDF]
Two lamprey glycroprotein hormone receptors (lGpH-R I and II) highly similar with gnathostome GpH-Rs were cloned from sea lamprey testes and thyroid, respectively.

Vitronectin Levels in Leukocyte-platelet Rich Fibrin, Injectable-platelet Rich Fibrin, and Serum: A Cross-sectional Study [PDF]
Introduction: Platelet-rich Fibrin (PRF) is an autologous platelet concentrate preparation containing several proteins that aid in healing. Vitronectin is one of these proteins that has not been quantified in all types of PRF. Various protocols have been
