Role of gamma-synuclein in microtubule regulation.

ABSTRACT: Gamma-synuclein is a neuronal protein found in peripheral and motor nerve systems. It becomes highly expressed in metastatic but not in primary tumor or normal tissues. The close association between gamma-synuclein expression and cancer spreading has been demonstrated in a broad range of malignancies. Our previous study showed that exogenous expression of gamma-synuclein in ovarian and breast cancer cells significantly enhanced cell migration and resistance to paclitaxel-induced apoptotic death. In our current research, we found that gamma-synuclein can affect microtubule properties and act as a functional microtubule associated protein. In vitro assays revealed that gamma-synuclein can bind and promote tubulin polymerization, induce the microtubule bundling and alter microtubule morpholog
