4E-BP1 expressed as a fusion with GFP (Green Fluorescent Protein) to act as a physiological substrate for FRAP1 (mTor).
For use in combination with the LanthaScreen™ Tb-anti-4E-BP1 [pThr46] Antibody (PV4757) to evaluate inhibitors in medium to high throughput screening applications. An optimized mTor assay buffer (PV4794) is also available.
