The Aspergillus nidulans nucAEndoG homologue is not involved in cell death

Abstract

Upon apoptosis induction, translocation of mammalian mitochondrial endonuclease G (EndoG) to the nucleus coincides with large-scale DNA fragmentation. Here, we describe for the first time a homologue of EndoG in filamentous fungi by investigating if the Aspergillus nidulans homologue of the EndoG gene, named nucAEndoG, is being activated during farnesol-induced cell death. Our results suggest that NucA is not involved in cell death, but it plays a role in the DNA-damaging response in A. nidulans. © 2011, American Society for Microbiology. All Rights Reserved.
