Purification and cell attachment activity of a D-galactose-binding lectin from the skin of sea hare, Aplysia kurodai.
A D-galactose-binding lectin which does not require Ca2+ or reducing reagents to induce activity was purified from skin of sea hare, Aplysia kurodai, by affinity chromatography. Skin lectin was confirmed to be a disulfide-bonded heteromultimer with molecular mass of 200 kDa, consisting of 28 kDa and 26 kDa subunits by SDS-PAGE and two-dimensional SDS-PAGE. Human rhabdomyosarcoma cells attached to and spread on plastic plates coated with lectin. Cell adhesion induced by lectin was completely inhibited by the addition of lactose.
