Three receptors for the H protein have been identified to date: complement regulatory molecule CD46, the signaling lymphocyte activation molecule (SLAM) and the cell adhesion molecule Nectin-4.
Normally, the SAP protein is expressed in the cytoplasm of T- and NK-cells, where it binds to the cytoplasmic domain of the surface receptor called signaling lymphocyte activation molecule (SLAM).
