    basic FUNCTION
  • involved in vascular smooth muscle cell proliferation
  • may be regulating cell apoptosis and cell differentiation
  • regulating tumor angiogenesis
  • can directly bind to NRP1 on endothelial cells, and can promote the NRP1/KDR-mediated signaling pathway as well as NRP1-mediated biological activities
  • induces phosphatidylserine exposure independent of alterations in mitochondrial potential, caspase activation, or cell death
  • stimulates monocyte migration in a dose-dependent manner but is not chemotactic for macrophages
  • may be involved in chemoattraction at sites of inflammation and may contribute to disease processes such as atherosclerosis
  • inhibits retinal pigment epithelial cell attachment, spreading, and migration
  • mediate inflammation and involved in axonal regeneration in the oxidized form and in axonal degeneration in the reduced form
  • may be associated with the pathogenesis of spinal cord injury
  • plays an important role in mesenchymal stromal cells immunoregulatory functions, which are depending on cell environment
  • LGALS1 and CD69 are a novel regulatory receptor-ligand pair that modulates Th17 effector cell differentiation and function
  • CELLULAR PROCESS cell life, proliferation/growth

    INTERACTION

    small molecule
    protein
  • binding to extracellular matrix proteins
  • binds LGALS3BP
  • selectively bound NRP1 via the carbohydrate-recognition domain, but did not bind FLT1, FLT4, KDR
  • is a novel ligand for MCAM and this interaction protects, in vitro, endothelial cells against apoptosis induced by LGALS1
  • prominent immunoregulatory function of LGALS1, is induction of apoptosis in activated T-cells by a process depending on the activity of SRC family tyrosine kinase, LCK
  • LGALS1 induces vascular permeability through the NRP1/FLT1 complex
  • interaction of LGALS1 and LGALS3 with CD6 and CD166/ALCAM might modulate some relevant aspects of T cell physiology
  • LGALS1, which encodes the galectin-1 protein, was a potential target of LYAR
  • cell & other
  • binding stronger to vascular smooth muscle cells
