The lectin hepatic binding protein has a specific binding capacity for desialylated serum glycoproteins and is limited to hepatocyte membranes. This binding capacity was reduced by approximately 60% in the neoplastic nodules which resulted from exposure of rat livers to N-2-acetylaminofluorene. The binding capacity of the primary hepatocellular carcinomas which resulted from this regimen was re...

Lectins are a class of ubiquitous proteins/glycoproteins that are abundantly found in nature. Lectins have unique carbohydrate binding property and hence have been exploited as drugs against various infectious diseases. We have isolated one such novel lectin from the fruit pulp of Aegle marmelos. The isolated lectin was partially characterised and its effect against Shigella dysenteriae infecti...

The toxic effect of Ricinus lectin RCA I, as estimated by the inhibition of [3H]leucine incorporation, was investigated on chick-embryo fibroblasts at different stages of development. There appeared to be a differential susceptibility of chick-embryo fibroblasts to lectin RCA I. Fibroblasts from 16-day embryos were the most sensitive to its toxic effect in terms of both concentration and time, ...

This review focuses on the extracellular proteoglycans. Special emphasis is placed on the structural features of their protein cores, their gene organization, and their transcriptional control. A simplified nomenclature comprising two broad groups of extracellular proteoglycans is offered: the small leucine-rich proteoglycans or SLRPs, pronounced "slurps, " and the modular proteoglycans. The fi...

A novel mammalian lectin activity responsive to monocytic differentiation is described in the human promyelocytic leukemia cell line HL-60. Glycoprotein binding indicates that the lectin recognizes both N-acetylneuraminic acid and galactose-terminating biantennary oligosaccharide structures. Lectin activity is independent of calcium and appears to reside in a Mr 17,000 intracellular membrane pr...

Linear polysaccharides are typically composed of repeating mono- or disaccharide units and are ubiquitous among living organisms. Polysaccharide diversity arises from chain-length variation, branching, and additional modifications. Structural diversity is associated with various physiological functions, which are often regulated by cognate polysaccharide-binding proteins. Proteins that interact...

Chitin is a fungal microbe-associated molecular pattern recognized in Arabidopsis by a lysin motif receptor kinase (LYK), AtCERK1. Previous research suggested that AtCERK1 is the major chitin receptor and mediates chitin-induced signaling through homodimerization and phosphorylation. However, the reported chitin binding affinity of AtCERK1 is quite low, suggesting another receptor with high chi...

Brugada syndrome (BrS) is an inherited arrhythmogenic disease with increased risk of sudden cardiac death. BrS considered a genetic disorder, and recent evidence suggests that it should be as oligogenic condition. Mutations are mainly related to the most SCN5A gene, encoding alpha subunit voltage-gated sodium channel (NaV1.5). usually lead impairment NaV1.5 functionality, which still main mecha...
