LGALS3BP and cancer: For example, galectin-binding protein/galactoside-binding soluble 3 binding protein (LGALS3BP/GAL3BP/LG3BP/90K/Mac-2BP) is a large, multitask-secreted, and hyperglycosylated 90 kDa protein that is expressed in the majority of human cells [145], including epithelial cells in breast and tear ducts, as well as in cancer cells [68].
