InnateDB Annotation
Lgals3 influences the course of malaria in a Plasmodium species-specific manner.
Lgals3 plays an important role in innate immunity to infection and colonization of Helicobacter pylori.
InnateDB Annotation from Orthologs
[Homo sapiens] LGALS3 exerts a regulatory role in innate immunity by diminishing IL-1beta production and thus affecting resistance to Rhodococcus equi infection.
[Homo sapiens] LGALS3, an abundant protein in macrophages and epithelial cells, belongs to a family of beta-galactoside-binding proteins, the galectins, with many proposed functions in immune response, development, differentiation, cancer and infection.
[Homo sapiens] LGALS3 is part of the galectin family of proteins that have emerged as autonomous bacteria-killing agents, pointing to a principal role of these proteins in innate immunity.
[Homo sapiens] LGALS3 influences the course of malaria in a Plasmodium species-specific manner. (Demonstrated in mice)
[Homo sapiens] LGALS1 and LGALS3 play opposing roles in the inflammatory responses to Trichomonas vaginalis infection.
Entrez Gene
Summary This gene does not have any Entrez summary - the following is the summary from its human ortholog ENSG00000131981:
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.[provided by RefSeq, Apr 2010]
