Fig. 4. Integrin activation caused Src-dependent SHIP2 phosphorylation in other
cell types. Anti-SHIP2 or control preimmune (Pre) IPs were blotted with
anti-phosphotyrosine (
-PY) or anti-SHIP2 antibodies. Samples were from
cells that were adherent (Ad), detached (D) or freshly re-plated (RP) on
collagen-I-coated dishes (6 µg/cm2) in the presence of DMSO (-)
or 1 µM Src inhibitor compound PD173956 (+) for 60 minutes. The arrows
point to tyrosine-phosphorylated SHIP2. (A) SH-SY5Y neuroblastoma cells. (B)
MDCK cells.
