General description

Lectins are carbohydrate-binding proteins, omnipresent, found in fungi, plants and animals. These oligomeric proteins are characterized by the presence of a carbohydrate recognition domain.

Application

Lectin from Helix pomatia has been used to study its binding activities in Gyrodactylus derjavini parasitizing fins of Oncorhynchus mykiss.

Biochem/physiol Actions

Lectin is useful in glycoconjugate characterizing, imaging and targeting. Lectin participates in host recognition and tissue adhesion. Lectins shows resistance to proteolytic degradation in vivo.
HPA has anti-A human blood group specificity and has an affinity for terminal N-acetyl-α-D-galactosaminyl residues. Conjugates are prepared from affinity purified lectin.

Analysis Note

Where reported, agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, of a 1 mg/ml solution. This activity is the lowest concentration to agglutinate a 2% suspension of human blood group A erythrocytes after 1 hour incubation at 25 °C.

Human group-specific component protein (Gc protein) is a multifunctional serum protein which has three common allelic variants, Gc1F, Gc1S and Gc2 in humans. Gc1 contains an O-linked trisaccharide [sialic acid-galactose-N-acetylgalactosamine (GalNAc)] on the threonine420 (Thr420) residue and can be converted

Along with the cells that are exposed to radiation, non-irradiated cells can unveil radiation effects as a result of intercellular communication, which are collectively defined as radiation induced bystander effects (RIBE). Exosome-mediated signalling is one of the core mechanisms responsible
