The mammalian cytoskeleton is an internal framework of actin, tubulin, and intermediate filament proteins. Proteins of these three classes assemble non-covalently into filamentous polymers that suppor
Multi-cellular organisms eliminate individual cells through a self-destruct process known as apoptosis. Apoptosis is critical for proper development and maintenance of tissue homeostasis. The importan
Epithelial cells exhibit an apical–basolateral axis of polarity that is generated during embryogenesis, is maintained throughout adult life in the face of constant cell regeneration, and is perturbed
