Crystal structure of the N-terminal domain of human galectin-4
Structural highlights
FunctionLEG4_HUMAN Galectin that binds lactose and a related range of sugars. May be involved in the assembly of adherens junctions. Publication Abstract from PubMedGalectins are proteins involved in diverse cellular contexts due to their capacity to decipher and respond to the information encoded by beta-galactoside sugars. In particular, human galectin-4, normally expressed in the healthy gastrointestinal tract, displays differential expression in cancerous tissues and is considered a potential drug target for liver and lung cancer. Galectin-4 is a tandem-repeat galectin characterized by two carbohydrate recognition domains connected by a linker-peptide. Despite their relevance to cell function and pathogenesis, structural characterization of full-length tandem-repeat galectins has remained elusive. Here, we investigate galectin-4 using X-ray crystallography, small- and wide-angle X-ray scattering, molecular modelling, molecular dynamics simulations, and differential scanning fluorimetry assays and describe for the first time a structural model for human galectin-4. Our results provide insight into the structural role of the linker-peptide and shed light on the dynamic characteristics of the mechanism of carbohydrate recognition among tandem-repeat galectins.
