Compound class: Endogenous peptide in human, mouse or rat
Comment: Gal-1 is a mammalian lectin that is active in the immune system. Its participation in the induction of self-tolerance suggests that any altered activity could lead to a failure to select out autoreactive cells, which may be relevant to autoimmune disease pathogenesis.
