Stathmin-2/STMN2: Proteins and Enzymes

Stathmin-2 (STMN2), also known as superior cervical ganglion 10 protein (SCG10), is a 19 kDa microtubule-destabilizing protein that is preferentially expressed in neurons. It promotes neuronal proliferation and migration as well as neurite outgrowth. Stathmin-2 contains a membrane attachment region (aa 1-26), a regulatory domain (aa 39-96), and an overlapping coiled-coil domain (aa 75-179). It is subject to phosphorylation of multiple serines within the regulatory domain. Within aa 26-179, human Stathmin-2 shares 100% and 99% aa sequence identity with mouse and rat Stathmin-2, respectively.
