SHIP SH2 domain binds to the phosphorylated mM (p-ITIM) of other inhibitory co-receptors (gp49Bl) (Kuroiwa etal, 1998) and to the p-ITIM-like motif of the adhesion receptor, PECAM-1 (Pumphrey et al., 1999), furthermore, in vitro it binds to the phosphorylated immimoreceptor tyrosine based activation motifs (p-TTAM) within the p and y subunits of the high affinity IgE receptor (Kimura et al. 1997)), and the zeta chain of T cell receptor (Osborne et al, 1996). However, in vivo coprecipitation of these molecules was not observed. 

Platelets also express adhesion receptors of the selectin gene family (P-selectin) and of the immunoglobulin gene superfamily (PECAM-1 and ICAM-2) (6). Expression of PECAM-1 and ICAM-2 may play a role in platelet interactions with endothelial cells and leukocytes, respectively.

The interaction of the various aP integrin complexes with ICAMs results in firm attachment and spreading. Subsequent VCAM-1-integrin and PECAM-1-integrin interactions are involved in leucocyte transmigration through endothelial cell junctions into the extravascular space. Leucocytes can thence proceed to interact with target cells and initiate inflammatory processes. 

VE)-cadherin and platelet endothelial cell adhesion molecule-1 (PECAM-1). VE-cadherin is an endothelial-specific Ca " -regulated protein that is linked to the cytoskeleton via catenins (Fig. 1). PECAM-1, also known as CD31, is a key participant in the migration of blood-borne cells across the BBB. Changes in the adherent junction proteins can lead to increased paracellular permeability (Abbruscato and Davis, 1999) and leukocyte trafficking in the CNS (Newman, 1994 Garrido-Urbani et al., 2008).
