IPod for iPod 5G of Irish rock band U2. Like its predecessor, this iPod has engraved the signatures of the four members of the band on its back, but this one was the first time the company changed the colour of the metal (not silver but black). This iPod was only available with 30GB of storage capacity. The special edition entitled purchasers to an exclusive video with 33 minutes of interviews and performance by U2, downloadable from the iTunes Store. In September 2007, during a lawsuit with patent holding company Burst.com, Apple drew attention to a patent for a similar device
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,
