Fungal amino acid biosynthesis has to be coordinated with amino acid uptake as well as protein degradation. A global regulator that connects amino acid biosynthesis and developmental programs is the transcription factor CpcA/Gcn4p. This transcriptional activator is conserved within the fungal kingdom and the cellular levels of this protein are carefully regulated. Deletion of the encoding cpcA gene in the opportunistic pathogen Aspergillus fumigatus results in impaired virulence in immuno-compromised mice, suggesting a role of the cross-pathway control system in fungal pathogenicity."],["dc.identifier.doi","10.1080/13693780600898029"],["dc.identifier.isi","000242601400017"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/29246"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Taylor & Francis Ltd"],["dc.publisher.place","Abingdon"],["dc.relation.conference","2nd Advances against Aspergillosis Conference"],["dc.relation.eventlocation","Athens, GREECE"],["dc.relation.issn","1369-3786"],["dc.title","Amino acid acquisition, cross-pathway control, and virulence in Aspergillus"],["dc.type","conference_paper"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

A conserved signal transduction cascade linking environmental stress to amino acid homeostasis is the Cross-Pathway Control (CPC) system that acts via phosphorylation of the translation initiation factor eIF2 by a sensor kinase to elevate expression of a transcription factor. Ingestion of Aspergillus fumigatus conidia by macrophages does not trigger this stress response, suggesting that their phagosomal microenvironment is not deficient in amino acids. The cpcC gene encodes the CPC eIF2 alpha kinase, and deletion mutants show increased sensitivity towards amino acid starvation. CpcC is specifically required for the CPC response but has limited influence on the amount of phosphorylated eIF2 alpha. Strains deleted for the cpcC locus are not impaired in virulence in a murine model of pulmonary aspergillosis. Accordingly, basal expression of the Cross-Pathway Control transcriptional activator appears sufficient to support aspergillosis in this disease model. (c) 2008 Elsevier Inc.
