AB - Recognition proteins play an important role in the immunodefense
system of invertebrates. The haemolymph of the Slipper oyster, Crassostrea
iredalei, contains a heparin-binding protein with a molecular weight of
35 kDa as determined by SDS-PAGE analysis. The protein was purified using column
chromatography. This binding protein possesses a serine protease activity thus
it is capable of activating the prophenoloxidase-activating (proPO) system.
However, the protein lacks β-1,3-glucanase activity. Using rabbit antiserum
against the isolated protein in immunodiffusion and immunoblotting assays it
produced a single precipitant and a single band, respectively. However, N-terminal
amino acid sequence of BGBP: Threonine-Alanine-Arginine-Asparagine-Glutamic
acid-Alanine-Asparagine-Valine was similar to Cavortin (AAT44352) and extracellular
superoxide dismutase (AAY60161) from C. gigas.
