STMN3 (Stathmin 3): STMN3 is a protein that regulates microtubule dynamics by destabilizing microtubules. This function is essential for processes like cell division, intracellular transport, and cell movement. In neurons, STMN3 plays a role in axonal growth and synaptic function, and its dysregulation may be linked to neurodevelopmental and neurodegenerative disorders.
