Secondary Information

Protein Function Binds galactosides.eosinophil chemoattractant and activation factor.cell aggregation and adhesion, as well as apoptosis of tumor cells.Activates ERK1/2 phosphorylation inducing cytokine (IL-6, IL-8, IL-12) and chemokine (CCL2) production in mast and dendritic cells.
Biochemical Properties a tandem-repeat type galectin with two carbohydrate-recognition domains.two non-homologous N- and C-terminal CRDs joined by a short polypeptide called the linker domain. four –OH groups of the β-galactoside residue forms the critical hydrogen bonds with highly conserved residues within the galectin CRD.In N terminal carbohydrate recognition domain,hydrogen bond is formed by N and H with O4 of galactose and an additional hydrogen bond between O6 of galactose and N completes the interaction.
Significance in milk Galectin 9 is a tandem repeat member of Gal involved in cell activation, pathogen destruction and immunosuppression.Galectin 9 secretion in cow milk a marker for homostasis and health.
