HacA-independent induction of chaperone-encoding gene bipA in Aspergillus niger strains overproducing membrane proteins.

Appl Environ Microbiol

School of Biology, University of Nottingham, University Park, Nottingham NG7 2RD, United Kingdom.

Published: January 2006

Transcription of two unfolded protein response genes, hacA and bipA, was examined in Aspergillus niger strains overproducing membrane proteins. Despite elevated bipA mRNA levels, no 5'-truncated hacA transcript was detected, raising the possibility of a hacA-independent induction of bipA mRNA under the stress of membrane protein overproduction in A. niger.
