We have isolated a novel phospholipid/ganglioside-binding protein from rabbit sera or platelet-free plasma. Using an affinity chromatography of a commercial gel (Sephacryl S-series gel, Pharmacia) column and a preparative polyacrylamide gel electrophoresis, the protein can be easily purified. The protein agglutinates human red cells irrespective of the ABO blood types, and its hemagglutination reaction is specifically inhibited by some phospholipids (phosphatidylserine and phosphatidylglycerol) and ganglioside (N-acetylneuraminyl-galactosylglucosyl ceramide, GM3). The hemagglutination and its inhibition reactions are independent on any divalent cations (Ca2+, Mg2+, Mn2+, Ni2+). The protein seems to be assembled as multimers of disulfide-bonded molecular of 86 kDa and 59 kDa subunits.

D010743 Phospholipids Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system. Phosphatides,Phospholipid
D011817 Rabbits A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.
