endogenous association between PABPC1 and IRS-1 or IRS-2. Co-immunoprecipitation analysis also showed that PABPC1 specifically associated with IRS-1 but not with IRS-2 (Fig. 1C). irs1-eif4e 3 PABPC1 4 western blot western blot Immuno blot Immuno blot experimental particp experimental participant identification experimental particp unspecified role unspecified role prey prey living cell living cell physiological level physiological level endogenous level endogenous endogenous endogenous level IRS1 5 western blot western blot Immuno blot Immuno blot experimental particp experimental participant identification experimental particp unspecified role unspecified role bait bait living cell living cell physiological level physiological level endogenous level endogenous endogenous endogenous level EIF4F 6 western blot western blot Immuno blot Immuno blot experimental particp experimental participant identification experimental particp unspecified role unspecified role prey prey living cell living cell physiological level physiological level endogenous level endogenous endogenous endogenous level association association f3 homomint mint we next examined whether components of cytoplasmic cap-binding protein also interact with IRS-1 (Fig. 3). We found that IRS-1 interacts with eIF4G and eIF4E in both serum-starved and IGF-I-stimulated MCF-7 cells. In contrast, we could not detect the association between IRS-1 and 4EBP1, which sequesters eIF4E in the eIF4E-4EBP1 complexes from mRNPs [32,33], indicating that IRS-1 certainly interacts with RNA-bound eIF4E rather than the eIF4E-4EBP1 complexes. Furthermore, our results revealed that the interactions of IRS-1 with both PABPC1 and eIFs were abolished by RNase A treatment, whereas the protein-protein interaction of IRS-1 with a p85 regulatory subunit of PI3K was not affected. These results suggest that IRS-1 is incorporated into mRNP complexes. irs1-pabpc1-3 2 PABPC1 4 western blot western blot Immuno blot Immuno blot experimental particp experimental participant identification experimental particp unspecified role unspecified role prey prey living cell living cell physiological level physiological level endogenous level endogenous endogenous endogenous level IRS1 7 anti tag western anti tag western blot anti tag western experimental particp experimental participant identification experimental particp unspecified role unspecified role bait bait over-expressed over expressed level over-expressed living cell living cell flag tag flag tag flag tag FLAG-tagged FLAG DYKDDDDKV epitope tag DYKDDDDKV epitope tag FLAG FLAG-tagged undetermined undetermined sequence position undetermined undetermined undetermined sequence position undetermined physical association physical association f1b homomint mint
