Furthermore, overexpression of FIP200 reduced TSC1-TSC2 complex formation, although knockdown of endogenous FIP200 by RNA interference did not affect TSC1-TSC2 complex formation

Immunofluorescence microscopy and subcellular fractionation, either upon forced PIASy expression or in the absence of PIASy, revealed that interaction with PIASy redistributes FIP200 from the cytoplasm to the nucleus, correlating with abrogation of FIP200 regulation of TSC/S6K signaling
