Plastin 1 binds to keratin and is required for terminal web assembly in the intestinal epithelium (2009)
Journal Article
Grimm-Gunter, E. M. S., Grimm-Guenter, E. S., Ferrary, E., Grimm-Günter, E. S., Hurbain, I., Louvard, D., …Smyth, N. (2009). Plastin 1 binds to keratin and is required for terminal web assembly in the intestinal epithelium. Molecular Biology of the Cell, 20(10), 2549-2562. https://doi.org/10.1091/mbc.e08-10-1030

Plastin 1 (I-plastin, fimbrin) along with villin and espin is a prominent actin-bundling protein of the intestinal brush border microvilli. We demonstrate here that plastin 1 accumulates in the terminal web and interacts with keratin 19, possibly con...

Characterization of RhoBTB-dependent Cul3 ubiquitin ligase complexes - Evidence for an autoregulatory mechanism (2008)
Journal Article

RhoBTB proteins are atypical members of the Rho family of small GTPases. Two of the three RhoBTB proteins, RhoBTB1 and RhoBTB2, have been proposed as tumor suppressors and might function as adaptors of Cul3-dependent ubiquitin ligase complexes. Using...

Linking Ras to myosin function: RasGEF Q, a Dictyostelium exchange factor for RasB, affects myosin II functions (2008)
Journal Article
Mondal, S., Bakthavatsalam, D., Steimle, P., Gassen, B., Rivero, F., & Noegel, A. A. (2008). Linking Ras to myosin function: RasGEF Q, a Dictyostelium exchange factor for RasB, affects myosin II functions. Journal of Cell Biology, 181(5), 747-760. https://doi.org/10.1083/jcb.200710111

Ras guanine nucleotide exchange factor (GEF) Q, a nucleotide exchange factor from Dictyostelium discoideum, is a 143-kD protein containing RasGEF domains and a DEP domain. We show that RasGEF Q can bind to F-actin, has the potential to form complexes...

Dictyostelium Sun-1 connects the centrosome to chromatin and ensures genome stability (2008)
Journal Article

The centrosome-nucleus attachment is a prerequisite for faithful chromosome segregation during mitosis. We addressed the function of the nuclear envelope (NE) protein Sun-1 in centrosome-nucleus connection and the maintenance of genome stability in D...
