Item Cytoplasmic foci at the crossroads of artifactual science and biological function(2016-05) Zhao, Alice; Marcotte, Edward M.; Ellington, Andrew D; Zhang, Yan J; Appling, Dean R; Iyer, Vishwanath RDeciphering protein interaction and compartmentalization is crucial to understanding the molecular mechanisms that drive biological processes. Using various high throughput approaches, we have managed to score subcellular dynamic protein re-organization into supramolecular structures and map physical association networks to discover protein complexes on a proteome-wide level. However, the case by case studies of some of these novel structures and interactions reveal difficulties in interpreting their biological basis. This study offers insights into limits inherent in the molecular techniques used to investigate subcellular structures and protein interactions, describing a set of cautionary tales and critical analysis for deciphering cases of confounding data from orthogonal approaches. This study also offers a new experimental technique for high-throughput imaging assays with mammalian cell lines.
