    ..These findings suggest that Sam68 may be a modulator of tyrosine kinase activity in vivo and a signaling requirement for mammary tumorigenesis and metastasis. ..

    ..More broadly, the inhibition of PRMT5 may be used therapeutically to manipulate PDGFR? bioavailability. ..
  3. Calabretta S, Richard S. Emerging Roles of Disordered Sequences in RNA-Binding Proteins. Trends Biochem Sci. 2015;40:662-72 pubmed publisher
    ..Herein, we discuss the role of disordered sequences in RBPs, their function in RNPs and protein networks, as well as their regulation by post-translational modifications and how RBP deregulation leads to disease. ..
  4. Li N, Richard S. Sam68 functions as a transcriptional coactivator of the p53 tumor suppressor. Nucleic Acids Res. 2016;44:8726-8741 pubmed
    ..These findings define a hitherto novel mechanism of action for Sam68 in governing p53 transcriptional activation, and represent the first report of Sam68 in the regulation of tumor suppressor activities. ..
