AAA ATPase p97/VCP: cellular functions, disease and therapeutic potential.

ABSTRACT: p97/VCP, a member of the AAA-ATPase super family, has been associated with a wide variety of essential cellular protein pathways com prising: (i) nuclear envelope reconstruction, (ii) cell cycle, (iii) Golgi reassembly, (iv) suppression of apoptosis and (v) DNA-damage response [1-6]. In addition, vasolin-containing protein (VCP) dislodges the ubiquitinated proteins from the endoplasmic reticulum (ER) and chaperones them to the cytosol for proteasomal degradation by endoplasmic reticulum-associated degradation (ERAD) [7]. The interactions of VCP in the endoplasmic reticulum-associated degradation (ERAD) pathway determine the substrate selection for proteasomal degradation. Moreover, the interaction with VCP is also required for the ubiquitination of substrate. VCP is phosphorylated by the m
