"Elevated Ser/Thr IRS-1 phosphorylation may inhibit insulin signalling by (1) downregulating IRS-1 protein levels through ubiquitination [XREF_BIBR - XREF_BIBR], (2) inhibiting the interaction between the tyrosine phosphorylated IR and the phosphotyrosine binding (PTB) domain of IRS-1 [XREF_BIBR - XREF_BIBR], or (3) interfering with the insulin stimulated interaction between IRS-1 and its downstream partner, the phosphatidylinositol 3-kinase (PI3-K) adaptor molecule p85 [XREF_BIBR, XREF_BIBR, XREF_BIBR]."
