Lectin with a hemagglutinating activity that is inhibited by galactose, lactose and EDTA (PubMed:15519291). Is calcium-dependent (PubMed:15519291). Shows effects on the renal function of isolated perfused rat kidneys by increasing both perfusion pressure (PP) and renal vascular resistance (RVR) (PubMed:16730365). In addition, the urinary flow and glomerular filtration rate (GFR) decreases significantly (PubMed:16730365). The changes observed may reflect direct injury to the glomerular and tubular renal cells, and the rise in permeability in the glomerular endothelial cells, may be the effect of interactions of C-type lectin with endothelial cells or due to release of other mediators by mesangial, tubular and endothelial cells (PubMed:16730365). Homodimer; disulfide-linked. Expressed by the venom gland. Belongs to the true venom lectin family.
