Biological aspects of signal transduction by cell adhesion receptors.
Cell adhesion receptors such as integrins, cadherins, selectins, and immunoglobulin family receptors profoundly modulate many signal transduction cascades. In this review we examine aspects of adhesion receptor signaling and how this impinges on key biological processes. We have chosen to focus on cell migration and on programmed cell death. We examine many of the cytoplasmic signaling molecules that interface with adhesion receptors, including focal adhesion kinase (FAK), phosphatidylinositol-3-kinase (PI3K), and elements of the Erk/MAP kinase pathway. In many cases these molecules impinge on both the regulation of cell movement and on control of apoptosis.
