FunctionGalactose-specific lectin which binds IgE. May mediate with the alpha-3, beta-1 integrin the stimulation by CSPG4 of endothelial cells migration. Together with DMBT1, required for terminal differentiation of columnar epithelial cells during early embryogenesis.
Tissue specificityA major expression is found in the colonic epithelium. It is also abundant in the activated macrophages.
Sequence similaritiesContains 1 galectin domain.
Cellular localizationNucleus. Cytoplasmic in adenomas and carcinomas. May be secreted by a non-classical secretory pathway and associate with the cell surface.
