| Research Abstract |
P97 is an essential AAA ATPase that is required for many cellular processes, and is identified as a causative gene for an autosomal dominant human disorder, inclusion body myopathy associated with Paget's disease of the bone and frontotemporal dementia. P97 possesses two AAA domains, in which disease-related mutations are mostly found in the N-terminal half. In this study, effects of mutations defective in ATPase activity in each AAA domain on the function of yeast p97 were analyzed. In this result, it is found that the C-terminal AAA domain is essential for p97 functions, which is modulated by the N-terminal AAA domain.
