Journal Article
Berger, M., Riley, D. R., Lutz, J., Khalil, J., Aburima, A., Naseem, K., …Lutz, D. (in press). Alterations in platelet alpha granule secretion and adhesion on collagen under flow in mice lacking the atypical Rho GTPase RhoBTB3. Cells, 8(2), 149. doi:10.3390/cells8020149

Typical Rho GTPases, like Rac1, Cdc42 and RhoA, act as molecular switches regulating various aspects of platelet cytoskeleton reorganization. The loss of these enzymes results in reduced platelet functionality. Atypical Rho GTPases of the RhoBTB su... Read More
