Background

STMN2 (Stathmin-2 or SCG10/Scgn10) belongs to stathmin family of proteins which are known to bind tubulin for acting as a sequestering agents and for promoting microtubule disassembly. STMN2 is a membrane-associated neuronal protein expressed mainly during development and its expression correlates with neurite outgrowth. STMN2 possesses a unique N-terminal domain that is critical for membrane binding, is responsible for STMN2 localization to the Golgi complex and is important in its targeting to growth cones. STMN2 localize to perinuclear cytoplasm, axons, and growth cones of developing neurons, and exists in soluble as well as membrane-bound forms. STMN2 interacts with ITMC2, as well as MAPK8, and when phosphorylated by MAPK8, it act as regulator of microtubule stability which controls neurite length in cortical neurons. Unlike other stathmins, STMN2 acts in two ways to promote microtubule dynamics: it stabilizes microtubules at their plus end and promotes microtubule catastrophe at their minus end. In the developing brain, STMN2 negatively regulates the rate of exit from multipolar stage and retards radial migration from the ventricular zone. Reduced STMN2 expression is associated with Down's syndrome and Alzheimer's disease.
