Get on the exosome bus with ALIX

Nat Cell Biol. 2012 Jun 29;14(7):654-5. doi: 10.1038/ncb2530.


Exosomes have a growing inventory of functions, but the mechanism of protein sorting into exosomes has been unclear. Now, a signal sequence first described in viral budding provides just such a cargo sorting mechanism, revealing closer-than-expected parallelism between exosome biogenesis and the ESCRT-dependent endolysosomal pathway.
