Tubulin Post-Translational Modifications Are Altered By Changes In Actin-Myosin Contractility In Non-Muscle Cells, James Mcgee Jun 2016

Tubulin Post-Translational Modifications Are Altered By Changes In Actin-Myosin Contractility In Non-Muscle Cells, James Mcgee

Honors Theses

All cells regulate their contractility by the interaction of actin and myosin. In non-muscle cells, however, this interaction is regulated by rho, a GTPase, which is the upstream effector for multiple pathways. Cell contractility increases when rho is active, and prior research has shown the depolymerization of microtubules (MTs) activates rho. Microtubules play a role in many cellular functions and it is thought that either associations with MT-associated proteins and/or post-translational modifications to tubulin regulate MT functions. Numerous post-translational modifications (PTMs) to microtubules have been identified, but their roles are not well understood. A possible relationship between changes in ...
