CC   -!- FUNCTION: Mannose-binding lectin which recognizes specific carbohydrate
CC       structures and agglutinates a variety of animal cells by binding to
CC       cell-surface glycoproteins and glycolipids. May be a calcium-dependent
CC       lectin (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- SIMILARITY: Belongs to the true venom lectin family. {ECO:0000305}.
