THE PUB DOMAIN FUNCTIONS AS A P97 BINDING MODULE IN HUMAN PEPTIDE N-GLYCANASE.
OverviewOverview
The AAA ATPase p97 is a ubiquitin-selective molecular machine involved in, multiple cellular processes, including protein degradation through the, ubiquitin-proteasome system and homotypic membrane fusion. Specific p97, functions are mediated by a variety of cofactors, among them peptide, N-glycanase, an enzyme that removes glycans from misfolded glycoproteins., Here we report the three-dimensional structure of the aminoterminal PUB, domain of human peptide N-glycanase. We demonstrate that the PUB domain is, a novel p97 binding module interacting with the D1 and/or D2 ATPase, domains of p97 and identify an evolutionary conserved surface patch, required for p97 binding. Furthermore, we show that the PUB and UBX, domains do not bind to p97 in a mutually exclusive manner. Our results, suggest that PUB domain-containing proteins constitute a widespread family, of diverse p97 cofactors.
