    The E3 ligase TRAF4 Promotes IGF Signaling by Mediating Atypical Ubiquitination of IRS-1. (PubMed, J Biol Chem)
    Overexpression of TRAF4 enhances IGF1-induced IGFR-IRS-1 interaction, IRS-1 tyrosine phosphorylation, and downstream effector protein activation while mutation of IRS-1 ubiquitination sites completely abolishes these effects. Altogether, our studies demonstrate that non-proteolytic ubiquitination of IRS-1 is a key step in conveying IGF-1 stimulation from IGFR to IRS-1.
