Supplementary information

Galectin-9 also known as Gal-9 or LGALS9 is a Β-galactoside-binding lectin with a molecular mass of around 40 kDa. It shows expression in various tissues including the thymus spleen and liver. The galectin-9 protein is involved in cell-cell and cell-matrix interactions where it binds to glycoproteins and glycolipids. Researchers commonly use methods like Galectin-9 ELISA to measure its levels in different biological samples.
Biological function summary

Galectins like galectin-9 play essential roles in regulating diverse immune responses. Galectin-9 acts within the immune system by modulating inflammation and apoptosis. It acts as both a pro-apoptotic factor for T cells and a protein mediator in innate immune functions. Galectin-9 proteins can form complexes with other lectins and cell surface receptors contributing to cellular signaling processes.

Pathways

Galectin-9 is integral to the immune system's functional networks. It participates in the T-cell regulation pathways and the innate immunity pathways. In these pathways it interacts with other proteins like TIM-3 which mediates T-cell apoptosis and contributes to immune tolerance. These interaction networks play important roles in maintaining the body's immune homeostasis.

Galectin-9 has associations with autoimmune diseases and cancer. Its regulatory effects on T cells connect it to autoimmune conditions where abnormal T-cell activation occurs. In cancer the alteration in galectin-9 expression levels affects tumor immunity. The interaction of galectin-9 with other proteins like TIM-3 is important in cancer progression making it a target of interest for therapeutic interventions.

Target data

Binds galactosides (PubMed : 18005988). Has high affinity for the Forssman pentasaccharide (PubMed : 18005988). Ligand for HAVCR2/TIM3 (PubMed : 16286920). Binding to HAVCR2 induces T-helper type 1 lymphocyte (Th1) death (PubMed : 16286920). Also stimulates bactericidal activity in infected macrophages by causing macrophage activation and IL1B secretion which restricts intracellular bacterial growth (By similarity). Ligand for P4HB; the interaction retains P4HB at the cell surface of Th2 T-helper cells, increasing disulfide reductase activity at the plasma membrane, altering the plasma membrane redox state and enhancing cell migration (PubMed : 21670307). Ligand for CD44; the interaction enhances binding of SMAD3 to the FOXP3 promoter, leading to up-regulation of FOXP3 expression and increased induced regulatory T (iTreg) cell stability and suppressive function (By similarity). Promotes ability of mesenchymal stromal cells to suppress T-cell proliferation (PubMed : 23817958). Expands regulatory T-cells and induces cytotoxic T-cell apoptosis following virus infection (PubMed : 20209097). Activates ERK1/2 phosphorylation inducing cytokine (IL-6, IL-8, IL-12) and chemokine (CCL2) production in mast and dendritic cells (PubMed : 16116184, PubMed : 24465902). Inhibits degranulation and induces apoptosis of mast cells (PubMed : 24465902). Induces maturation and migration of dendritic cells (PubMed : 16116184, PubMed : 25754930). Inhibits natural killer (NK) cell function (PubMed : 23408620). Can transform NK cell phenotype from peripheral to decidual during pregnancy (PubMed : 25578313). Astrocyte derived galectin-9 enhances microglial TNF production (By similarity). May play a role in thymocyte-epithelial interactions relevant to the biology of the thymus. May provide the molecular basis for urate flux across cell membranes, allowing urate that is formed during purine metabolism to efflux from cells and serving as an electrogenic transporter that plays an important role in renal and gastrointestinal urate excretion (By similarity). Highly selective to the anion urate (By similarity).. Isoform 2. Acts as an eosinophil chemoattractant (PubMed : 9642261). It also inhibits angiogenesis (PubMed : 24333696). Suppresses IFNG production by natural killer cells (By similarity).
