The disease mechanism underlying p97 ATPase malfunction remains unclear. To understand how the mutation alters the ATPase regulation, we assembled a full-length p97R155H with its p47 cofactor and first visualized their structures using single-particle cryo-EM. More than one-third of the population was the dodecameric form. Nucleotide presence dissociates the dodecamer into two hexamers for its highly elevated function. The N-domains of the p97R155H mutant all show up configurations in ADP- or ATP\u03b3S-bound states. Our functional and structural analyses showed that the p47 binding is likely to impact the p97R155H ATPase activities via changing the conformations of arginine fingers. These functional and structural analyses underline the ATPase dysregulation with the miscommunication between the functional modules of the p97R155H.<\/jats:p>","DOI":"10.3390\/ijms22158079","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T11:12:52Z","timestamp":1627470772000},"page":"8079","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Structural and Functional Analysis of Disease-Linked p97 ATPase Mutant Complexes"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8047-2029","authenticated-orcid":false,"given":"Purbasha","family":"Nandi","sequence":"first","affiliation":[{"name":"Biodesign Center for Applied Structural Discovery, School of Molecular Sciences, Arizona State University, Tempe, AZ 85287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0829-1821","authenticated-orcid":false,"given":"Shan","family":"Li","sequence":"additional","affiliation":[{"name":"Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rod Carlo A.","family":"Columbres","sequence":"additional","affiliation":[{"name":"Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dewight R.","family":"Williams","sequence":"additional","affiliation":[{"name":"Eyring Materials Center, Arizona State University, Tempe, AZ 85287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Ping","family":"Poh","sequence":"additional","affiliation":[{"name":"Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsui-Fen","family":"Chou","sequence":"additional","affiliation":[{"name":"Division of Biology and Biological Engineering, California Institute of Technology, Pasadena, CA 91125, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8608-7650","authenticated-orcid":false,"given":"Po-Lin","family":"Chiu","sequence":"additional","affiliation":[{"name":"Biodesign Center for Applied Structural Discovery, School of Molecular Sciences, Arizona State University, Tempe, AZ 85287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1016\/j.jsb.2003.10.010","article-title":"Evolutionary history and higher order classification of AAA+ ATPases","volume":"146","author":"Iyer","year":"2004","journal-title":"J.
