We observed that cell adhesion Sion leads to tyrosine phosphorylation of SHIP1, but fMLP stimulation lead to an increase is not apparent Increase in tyrosine phosphorylation of SHIP1. We have also observed that FAK may with SHIP1 and Lyn on Zelladh Commission and interact with � Integrin sion both in the suspension and Zelladh. This indicates that adhesion results in the recruitment of SHIP1 to the membrane, where it is on PtdInsP3 w During Zelladh can act Sion produced.
