Galectin-3/LGALS3 Protein, Mouse

Galectin-3 (LGALS3) is a multifunctional protein predicted to engage in diverse activities, including IgE binding, advanced glycation end-product receptor activity, and signaling receptor binding. Its involvement in negative regulation of the T cell receptor signaling pathway, endocytosis, and lymphocyte activation underscores its crucial role in modulating immune responses. Positioned in various cellular components, including the external side of the plasma membrane, glial cell projections, and immunological synapses, Galectin-3 operates upstream of processes such as extracellular matrix organization and skeletal system development. Widely expressed in anatomical structures like the alimentary and genitourinary systems, respiratory system, skeleton, and skin, Galectin-3 holds significance in diverse physiological contexts. Notably, it exhibits biased expression in specific tissues, such as the colon and duodenum, suggesting a specialized role in these anatomical regions. Studies on this protein may provide insights into its implications in conditions like asthma and fatty liver disease.
