JUNQ and IPOD IPOD may serve not only as a sequestration site, but also as a functional compartment. The IPOD is a non- membrane bound cellular site, which in yeast is located by the vacuole. FRAP and FLIP assays revealed that proteins in the IPOD are tightly packed, in-soluble and don't exchange with the cytosol. Amyloidogenic proteins, such as the Huntingtin protein, are the IPOD's substrates. Misfolded proteins must be non-ubiquitinated to be sorted to the IPOD. Ubiquitination of an otherwise IPOD substrate, such as the RNQ1 fungal prion, will result in its sequestration in the JUNQ inclusion. Upon accumulation of misfolded proteins,
