To drive matrix translocation the TIM23 complex recruits the presequence translocase-associated motor (PAM) with the matrix heat shock protein 70 (mtHsp70) as central subunit. Activity and localization of mtHsp70 are regulated by four membrane-associated cochaperones: the adaptor protein Tim44, the stimulatory J-complex Pam18/Pam16, and Pam17. It has been proposed that Tim44 serves as molecular platform to localize mtHsp70 and the J-complex at the TIM23 complex, but it is unknown how Pam17 interacts with the translocase. We generated conditional tim44 yeast mutants and selected a mutant allele, which differentially affects the association of PAM modules with TIM23. In tim44-804 mitochondria, the interaction of the J-complex with the TIM23 complex is impaired, whereas unexpectedly the binding of Pam17 is increased. Pam17 interacts with the channel protein Tim23, revealing a new interaction site between TIM23 and PAM. Thus, the motor PAM is composed of functional modules that bind to different sites of the translocase. We suggest that Tim44 is not simply a scaffold for binding of motor subunits but plays a differential role in the recruitment of PAM modules to the inner membrane translocase."],["dc.identifier.doi","10.1091/mbc.E07-12-1226"],["dc.identifier.gro","3143286"],["dc.identifier.isi","000259155200028"],["dc.identifier.pmid","18400944"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/783"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.eissn","1939-4586"],["dc.relation.issn","1059-1524"],["dc.title","Mitochondrial protein import motor: Differential role of Tim44 in the recruitment of Pam17 and J-complex to the presequence translocase"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2008Conference Abstract [["dc.bibliographiccitation.journal","Biochimica et Biophysica Acta (BBA) - Bioenergetics"],["dc.bibliographiccitation.volume","1777"],["dc.contributor.author","Wagner, Karina"],["dc.contributor.author","Guiard, Bernard"],["dc.contributor.author","Brandner, Katrin"],["dc.contributor.author","Pfanner, Nikolaus"],["dc.contributor.author","Rehling, Peter"],["dc.date.accessioned","2018-11-07T11:12:55Z"],["dc.date.available","2018-11-07T11:12:55Z"],["dc.date.issued","2008"],["dc.format.extent","S42"],["dc.identifier.doi","10.1016/j.bbabio.2008.05.168"],["dc.identifier.isi","000258037700158"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/53773"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Elsevier Science Bv"],["dc.publisher.place","Amsterdam"],["dc.relation.conference","15th European Bioenergetic Conference"],["dc.relation.eventlocation","Trinity Coll, Dublin, IRELAND"],["dc.relation.issn","0005-2728"],["dc.title","Biogenesis of the mitochondrial carrier translocase"],["dc.type","conference_abstract"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]Details DOI WOS2011Journal Article Research Paper [["dc.bibliographiccitation.firstpage","643"],["dc.bibliographiccitation.issue","4"],["dc.bibliographiccitation.journal","The Journal of Cell Biology"],["dc.bibliographiccitation.lastpage","656"],["dc.bibliographiccitation.volume","195"],["dc.contributor.author","Schulz, Christian"],["dc.contributor.author","Lytovchenko, Oleksandr"],["dc.contributor.author","Melin, Jonathan"],["dc.contributor.author","Chacinska, Agnieszka"],["dc.contributor.author","Guiard, Bernard"],["dc.contributor.author","Neumann, Piotr"],["dc.contributor.author","Ficner, Ralf"],["dc.contributor.author","Jahn, Olaf"],["dc.contributor.author","Schmidt, Bernhard"],["dc.contributor.author","Rehling, Peter"],["dc.date.accessioned","2017-09-07T11:43:19Z"],["dc.date.available","2017-09-07T11:43:19Z"],["dc.date.issued","2011"],["dc.description.abstract","N-terminal targeting signals (presequences) direct proteins across the TOM complex in the outer mitochondrial membrane and the TIM23 complex in the inner mitochondrial membrane.

Different views exist about the role played by the Tim9-Tim10 complex in translocation of the AAC precursor across the outer membrane. For this report we have generated a new tim10 yeast mutant that leads to a strong defect in AAC import into mitochondria. Thereby, for the first time, authentic AAC is stably arrested in the translocase complex of the outer membrane (TOM), as shown by antibody shift blue native electrophoresis. Surprisingly, AAC is still associated with the receptors Tom70 and Tom20 when the function of Tim10 is impaired.
