Abstract: | The AAA-ATPase Cdc48/p97 controls a large array of cellular functions including protein degradation, cell division, membrane fusion through its ability to interact with and control the fate of ubiquitylated proteins. More recently, Cdc48/p97 also appeared to be involved in autophagy, a catabolic cell response that has long been viewed as completely distinct from the Ubiquitine/Proteasome System. In particular, conjugation by ubiquitin or ubiquitin-like proteins as well as ubiquitin binding proteins such as Cdc48/p97 and its cofactors can target degradation by both catabolic pathways. This review will focus on the recently described functions of Cdc48/p97 in autophagosome biogenesis as well as selective autophagy. |
