Calcineurin localizes to the hyphal septum in Aspergillus fumigatus: implications for septum formation and conidiophore development

Eukaryot Cell. 2008 Sep;7(9):1606-10. doi: 10.1128/EC.00200-08. Epub 2008 Jul 7.

Abstract

A functional calcineurin A fusion to enhanced green fluorescent protein (EGFP), CnaA-EGFP, was expressed in the Aspergillus fumigatus DeltacnaA mutant. CnaA-EGFP localized in actively growing hyphal tips, at the septa, and at junctions between the vesicle and phialides in an actin-dependent manner. This is the first study to implicate calcineurin in septum formation and conidiophore development of a filamentous fungus.
