The Saxton lab studies mechanisms that drive intracellular transport and cytoplasmic organization, using Drosophila as a model organism. To generate and maintain proper cytoplasmic order and thus their complex functions, cells use microtubules and force-generating motor proteins to transport RNAs, proteins, mitochondria and other organelles to appropriate locations. Neurons are especially dependent on such microtubule-based cytoplasmic transport, because their signaling functions rely on extraordinarily long cytoplasmic extensions (axons and dendrites) that require import of many components from their cell bodies ...
