Galectin-3 (LGALS3) Antibody – Mouse Monoclonal

This gene encodes a member of the galectin family of carbohydrate binding proteins. Members of this protein family have an affinity for beta-galactosides. The encoded protein is characterized by an N-terminal proline-rich tandem repeat domain and a single C-terminal carbohydrate recognition domain. This protein can self-associate through the N-terminal domain allowing it to bind to multivalent saccharide ligands. This protein localizes to the extracellular matrix, the cytoplasm and the nucleus. This protein plays a role in numerous cellular functions including apoptosis, innate immunity, cell adhesion and T-cell regulation. Alternate splicing results in multiple transcript variants.

Function: Galactose-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

By similarity. In the nucleus: acts as a pre-mRNA splicing factor. Involved in acute inflammatory responses including neutrophil activation and adhesion, chemoattraction of monocytes macrophages, opsonization of apoptotic neutrophils, and activation of mast cells. Ref.15 Ref.16 Ref.17

Subunit structure: Probably forms homo- or heterodimers. Interacts with DMBT1

By similarity. Forms a complex with the ITGA3, ITGB1 and CSPG4. Interacts with LGALS3BP, LYPD3, CYHR1 and UACA. Ref.14 Ref.15

Subcellular location: Cytoplasm. Nucleus. Secreted. Note: Secreted by a non-classical secretory pathway and associates with the cell surface. Ref.5 Ref.15 Ref.17

Tissue specificity: A major expression is found in the colonic epithelium. It is also abundant in the activated macrophages.

Sequence similarities: Contains 1 galectin domain.
