  • Title: Ras regulatory interactions: novel targets for anti-cancer intervention?
    Author: Prendergast GC, Gibbs JB.
    Journal: Bioessays; 1994 Mar; 16(3):187-91. PubMed ID: 8166672.
    Abstract:
    Advances in the understanding of Ras oncoprotein function suggest novel points for anti-tumor intervention. First, upstream-acting guanine nucleotide exchange factors and SH2/SH3 domain-containing adaptor proteins that link Ras with growth factor receptor tyrosine kinases have recently been characterized. Second, work on downstream-acting Ras effector functions including the Ras GTPase-activating protein (p120GAP) and the Raf kinase has revealed direct biochemical interactions that are functionally required for oncogenic Ras signalling. We summarize progress in these areas and discuss the potential for novel applications to anti-cancer chemotherapy.
