... curdlan or laminarin. Afterbinding of the carbohydrate to the receptor, the expression of the gene coding for the binding protein increases. In turn, the potential scavenger molecule, a fibrinogen-relatedpolypeptide, ... Expression of the (1fi3)-b-D-glucan-binding protein and the fibrinogen-likeprotein occurred in cells on the sponge surface, in the pin-acoderm. By Western blotting, the product of the fibrin-ogen-like ... domain as in the ficolins[21], or lectin as in the horseshoe crab [20], or a coiled-coildomain in angiopoietin [67], could be detected in the spongeprotein. The sponge fibrinogen-like protein...
