Comments concerning this interaction

Source was live Sf9 insect cells; proteins produced from baculovirus constructs.

Physical interaction of proteins expressed on the surface of cells is inferred from the aggregation of live cells.

Assay: cell aggregation. Addition of phospholipase-C disrupts interaction.
