[1] As part of the petivitelline fluid, PsSC is probably playing a role as a nutrient source for the developing embryo in Pomacea scalaris eggs.
[1] As a consequence, this perivitellin absorbs light throughout the visible range, a characteristic related to a photoprotective role in these aerially deposited eggs.
[1] Like most other studied perivitellins from Pomacea snails, PsSC is highly stable in a wide range of pH values and withstands gastrointestinal digestion, characteristics associated with an antinutritive defense system that deters predation by lowering the nutritional value of the eggs.
[2] Unlike ovorubin and PmPV1, PsSC is an active, strong lectin, recognizing glycosphingolipids (notably, the gangliosides GD1b, GT1b, and GD1a) and AB0 group antigens.
[2][3] Due to this activity, PsSC agglutinates red blood cells (notably those from rabbits and human A and B groups) as well as Gram-negative bacteria, indicating a putative immune role of this perivitellin.
