Galectins: a key intersection between glycobiology and immunology BJMBR
Rabinovich,G.A.; Riera,C.M.; Landa,C.A.; Sotomayor,C.E..
Galectins are a family of evolutionarily conserved animal lectins, widely distributed from lower invertebrates to mammals. They share sequence and structure similarities in the carbohydrate recognition domain and specificity for polylactosamine-enriched glycoconjugates. In the last few years significant experimental data have been accumulated concerning their participation in different biological processes requiring carbohydrate recognition such as cell adhesion, cell growth regulation, inflammation, immunomodulation, apoptosis and metastasis. In the present review we will discuss some exciting questions and advances in galectin research, highlighting the significance of these proteins in immunological processes and their implications in biomedical...

Isolation of a ß-galactoside-binding lectin from cat liver BJMBR
Franco-Fraguas,L.; Batista-Viera,F.; Carlsson,J..
A lectin from cat liver has been identified and purified by affinity chromatography on asialofetuin-Sepharose. One hundred micrograms of lectin was obtained from one cat liver with a purification factor of 1561. The lectin agglutinates trypsin-treated rabbit and cow erythrocytes. Hemagglutination was inhibited only by saccharides containing ß-galactosyl residues, of which the 1-amine-1-deoxy-ß-D-galactose was the most potent one by inhibiting hemagglutination at a concentration of 12.5 mM, followed by melibiose, trehalose and galactose. The lectin has a subunit molecular mass of 14.4 kDa determined by SDS-PAGE under reducing conditions and a pI of 4.85. Compared with the composition of lectins from calf heart and porcine heart, cat liver lectin contains...
