Hetzer M, et al. (2001) Distinct AAA-ATPase p97 complexes function in discrete steps of nuclear assembly. Nat Cell Biol 3(12):1086-91
Abstract: Although nuclear envelope (NE) assembly is known to require the GTPase Ran, the membrane fusion machinery involved is uncharacterized. NE assembly involves formation of a reticular network on chromatin, fusion of this network into a closed NE and subsequent expansion. Here we show that p97, an AAA-ATPase previously implicated in fusion of Golgi and transitional endoplasmic reticulum (ER) membranes together with the adaptor p47, has two discrete functions in NE assembly. Formation of a closed NE requires the p97-Ufd1-Npl4 complex, not previously implicated in membrane fusion. Subsequent NE growth involves a p97-p47 complex. This study provides the first insights into the molecular mechanisms and specificity of fusion events involved in NE formation.
