We present evidence for the expression of three alpha-dystroglycan glycoforms in skeletal muscle cells, including two minor glycoforms marked by either patent or latent reactivity with the N-acetylgalactosamine-specific lectin Vicia villosa agglutinin. Both minor glycoforms co-isolated with beta-dystroglycan, but not with other dystrophin/utrophin-glycoprotein complex components, suggesting tha...
The binding ability of anti-insulin-like growth factor Ι receptor (IGF-ΙR) single-chain variable fragments (scFvs) to IGF-IR was measured in the presence of plant lectins. Combinations of concanavalin A (Con A), wheat germ agglutinin (WGA), or peanut agglutinin (PNA) and 1H7 or 3B7 anti-IGF-ΙR scFv/phage antibodies that were previously produced and characterized were used. WGA inhibited binding...
In the present study ultrastructural localization of binding sites for 5 lectins was studied in rat liver cell surface membrane fractions. For this purpose ferritin-coupled Concanavalin A, wheat germ agglutinin, soybean agglutinin, Ricinus communis agglutinin 120 and Lotus tetragonolobus agglutinin I were used as probes for mannose, N-acetyl glucosamine, N-acetyl galactosamine, galactose and fu...
The lectin binding characteristics of goldfish retinal explants were examined by fluorescence microscopy. Neurites grown out from cultured retinal explants were found to bind concanavalin A, wheat germ agglutinin and ricin (agglutinin). The effects of tissue fixation on lectin binding to retinal explant neurites suggest that glycolipids may constitute the predominant ricin binding sites. A redu...
In W303-derived strains, disruption of FIG2 increased agglutinability of alpha cells, but not a cells, and did not alter expression of alpha-agglutinin, binding of 125I-labeled alpha-agglutinin, or mating efficiency. Fig2p overexpression led to alpha-cell-specfic suppression of agglutinability. These results imply that Fig2p is an indirect masker of the active sites in alpha-agglutinin.
Salivary agglutinin is a high molecular mass component of human saliva that binds Streptococcus mutans, an oral bacterium implicated in dental caries. To study its protein sequence, we isolated the agglutinin from human parotid saliva. After trypsin digestion, a portion was analyzed by matrix-assisted laser/desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), which gave the mo...
hemagglutination activity (enhanced lectin activity) not expressed by nonactivated platelets, and this agglutinin mediates the direct platelet-platelet interactions that cause the aggregation of thrombinactivated platelets. The enhanced agglutinin activity of thrombin-activated platelets is composed of two components: a plasma membrane-bound component and a soluble component.3 The expression of...
