Identification of galectin-3 as a factor in pre-mRNA splicing.

Identification of galectin-3 as a factor in pre-mRNA splicing.

Galectin-3 (M(r) approximately 35,000) is a galactose/lactose-specific lectin found in association with ribonucleoprotein complexes in many animal cells. Cell-free-splicing assays have been carried out to study the requirement for galectin-3 in RNA processing by HeLa cell nuclear extracts by using 32P-labeled MINX as the pre-mRNA substrate. Addition of saccharides that bind galectin-3 with high...

NUCLEAR AND CYTOPLASMIC LOCALIZATION OF GALECTIN-1 AND GALECTIN-3 AND THEIR ROLES IN PRE-mRNA SPLICING

Supportive Data for Galectin-3 as a Prognostic Factor in Coronary Artery Disease

Introduction: Galectin-3 is known as a biomarker in patients with heart failure. This protein participates in different mechanisms involved in atherosclerosis including inflammation and plaque formation. This study was conducted to investigate whether this factor could be a predictive biomarker for the severity of atherosclerosis. Materials and Methods: The study group consisted of 80 patients ...

Evidence for a role for galectin-1 in pre-mRNA splicing.

Galectins are a family of beta-galactoside-binding proteins that contain characteristic amino acid sequences in the carbohydrate recognition domain (CRD) of the polypeptide. The polypeptide of galectin-1 contains a single domain, the CRD. The polypeptide of galectin-3 has two domains, a carboxyl-terminal CRD fused onto a proline- and glycine-rich amino-terminal domain. In previous studies, we s...

Identification of galectin-1 and galectin-3 as novel partners for von Willebrand factor.

OBJECTIVE Although von Willebrand factor (VWF) is a heavily glycosylated protein, its potential to associate with glycan-binding proteins is poorly investigated. Here, we explored its interaction with the glycan-binding proteins galectin-1 and galectin-3. METHODS AND RESULTS Immunofluorescence analysis using Duolink proximity ligation assays revealed that VWF colocalizes with galectin-1 and g...
