Cell biology: A new dynamin superfamily protein remodels mitochondrial dynamics.

Abstract

Dynamin superfamily proteins mediate mitochondrial fusion in fungi and animals. A new study expands the taxonomic reach of this superfamily and provides insights into the roles these proteins play by investigating MfnL, a family member involved in trypanosomal mitochondrial dynamics. Importantly, MfnL occurs widely in eukaryotes and prokaryotes.
