Abstract 


Previous work showed that integrin stimulation triggers activation of the c-Abl tyrosine kinase and its transient localization to focal adhesions. We now report that plating cells on fibronectin triggers association of Grb2 with c-Abl, suggesting possible involvement of c-Abl with integrin activation of the MAP kinase pathway. Expression of a kinase-defective c-Abl specifically inhibited the transient induction of Erk2 activity following cell adhesion. Together with the known ability of activated, oncogenic forms of c-Abl to activate Ras and the MAP kinase pathway, these data suggest that c-Abl contributes to the integrin induction of MAP kinase activity.
