Why do cellular proteins linked to K63-polyubiquitin chains not associate with proteasomes?

Nathan JA, Tae Kim H, Ting L, Gygi SP, Goldberg AL

Although cellular proteins conjugated to K48-linked Ub chains are targeted to proteasomes, proteins conjugated to K63-ubiquitin chains are directed to lysosomes. However, pure 26S proteasomes bind and degrade K48- and K63-ubiquitinated substrates similarly. Therefore, we investigated why K63-ubiquitinated proteins are not degraded by proteasomes. We show that mammalian cells contain soluble factors that selectively bind to K63 chains and inhibit ... [more]
