A weaker but detectable binding to the SH3 domain of Grb2, however, was observed.
Shc, Gab1, Grb2, mSOS, and MAPK kinase (MEK-1)) known to be used by single-transmembrane receptor tyrosine kinases (RTKs) like the epidermal growth factor receptor (EGFR) (for a review see [ 6 ] ). When ERKs are activated after EGFR stimulation, an essential event is the sequential tyrosine phosphorylation of these intermediate proteins and their binding to the tyrosine phosphorylated EGFR before the GTP-loading of Ras.
Affinity-purified anti-α 2 β 1 integrin (MAB1988), anti-α v β 3 integrin (LM609), anti-MMP2 (MAB13405), and anti-VE-cadherin (MAB1989) monoclonal antibodies (mAbs) were purchased from Chemicon Intl; anti-Flt-1 (sc-316), anti-KDR (sc-6251), anti-Kinesin heavy chain (sc-13359), anti-Stanniocalcin (sc-14352), and anti-Grb2 were obtained from Santa Cruz Biotechnology Inc., and anti-β 1 integrin subunit mAbs (4B4), from Coulter Inc.
PTEN is altered or deleted in many human cancers [ 7 8 9 10 ] . In-vitro, cells that are deficient in PTEN show elevated PI-3Kinase signaling [ 11 ] . Reintroduction of PTEN in a variety of cancer cells, including glioma, breast, bladder and ovarian cancer cells, causes G1 arrest, inhibits tumorigenesis, and promotes anoikis [ 12 13 14 ] . Mechanistically, Akt activity is decreased, cell motility is decreased, expression of two cyclin-dependent kinase inhibitors p27 and p21 is increased, cyclin D1 is down-regulated, Rb phosphorylation is inhibited, and signaling via Grb2/SOS is suppressed [ 11 15 ] . The link between PTEN and cell growth is underscored by genetic experiments in mice.
Despite numerous reported differences, it does appear that diverse GPCRs share common mechanistic themes during ERK stimulation, including the tyrosine-phosphorylation of Shc and its complexing with Grb2, mSOS recruitment, the GTP-loading of Ras, and Raf-1 activation leading to MEK-1 phosphorylation [ 1 ] . However, the progression of each of these downstream events after GPCR stimulation depends first on the tyrosine phosphorylation of a membrane-bound protein that will be used as a scaffold, which will bind the other proteins (e.g.
