Protein was isolated using Passive Lysis Buffer (Promega), and RNA was purified applying TRIzol Reagent (Invitrogen). Western blotting, RT-PCR and immunoprecipitations Protein was electrophoresed in SDS-polyacrylamide, transferred to Hybond ECL nitrocellulose (Amersham), and probed with antibodies that recognize FLAG (Sigma, cat# F315, 1:5000), HA (Roche, cat# 11867423001, 1:1000), calnexin (StressGen, cat# SPA-860, 1:1000), UPF1 (ref. 7; 1:1000), STAU1 (a gift from the Ort lab; 1:2400), RFP (Abcam, cat# ab65865, 1:1000), GFP (Abcam, cat# ab1218, 1:1000) or STAU2 (Sigma, cat# HPA019155, 1:500). Immunoreactivity was assessed employing SuperSignal West Pico or Femto (Pierce Biotechnology). Right after autoradiography, films were quantitated employing ImageQuant (Molecular Dynamics). Reverse transcription (RT) and PCR amplification had been performed as previously described7. RT-PCR goods have been electrophoresed in 5 polyacrylamide and quantitated by PhosphorImaging (Molecular Dynamics). The five leftmost lanes of each figure represent 2fold serial dilutions of RNA. A standard curve was derived from these 5 lanes and utilised to calculate the relative abundance of each mRNA from various transfections. P values had been determined applying a one-tailed t-test. Immunoprecipitations have been performed7 utilizing anti-GFP (Abcam), anti-HA (Roche) or antiFLAG (Sigma). To ascertain IP and co-IP efficiencies, ImageQuant values that have been obtained by western blotting samples before or after IP were superimposed around the values obtained for the 3-fold serial dilutions of protein prior to IP which are supplied in the four leftmost lanes of every western blot. For every single protein, the worth following IP was normalized to the worth prior to IP, and values were then compared.Birtamimab See Supplementary Table 2, which lists IP and co-IP efficiencies for each and every experiment.Gefitinib Wound-healing assays Approaches were as described10.PMID:23614016 Cells were imaged using a Nikon Eclipse TE2000-U inverted fluorescence microscope.Author Manuscript Author Manuscript Author Manuscript Author ManuscriptSupplementary MaterialRefer to Net version on PubMed Central for supplementary material.AcknowledgmentsWe thank H.
