Lire la suite >Glycosylation is a group of post-translational modifications that displays a large variety of structures and are implicated in a plethora of biological processes. Therefore, studying glycosylation requires different technical approaches and reliable tools, lectins being part of them. Here, we describe the use of the recombinant mushroom lectin PVL to discriminate O-GlcNAcylation, a modification consisting in the attachment of a single N-acetylglucosamine residue to proteins confined within the cytosolic, nuclear and mitochondrial compartments. Recombinant PVL (Psathyrella velutina lectin) (rPVL) displays significantly stronger affinity for GlcNAc over Neu5Ac residues as verified by thermal shift assays and surface plasmon resonance experiments, being therefore an excellent alternative to WGA (wheat germ agglutinin). Labeling of rPVL with biotin or HRP (horseradish peroxidase) allows its useful and efficient utilization by western blot. The staining of whole cell lysates with labeled-rPVL was dramatically decreased in response to O-GlcNAc transferase knockdown and seen to increase after pharmacological blockade of O-GlcNAcase. Also, HRP-rPVL seemed to be more sensitive than the anti-O-GlcNAc antibody RL2. Thus, rPVL is a potent new tool to selectively detect O-GlcNAcylated proteins.Lire moins >
