The role of electron capture dissociation in biomolecular analysis.
The introduction of electron capture dissociation (ECD) to electrospray (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) constitutes a significant advance in theExpand

Phosphorylation-Dependent Binding of 14-3-3 to the Polarity Protein Par3 Regulates Cell Polarity in Mammalian Epithelia
The mammalian homologs of the C. elegans partitioning-defective (Par) proteins have been demonstrated to be necessary for establishment of cell polarity. In mammalian epithelia, the Par3/Par6/aPKCExpand
