Stathmin 2 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The STMN2 gene (Stathmin-2), also known as SCG10 (Superior Cervical Ganglion 10), encodes a neuronal microtubule-destabilizing protein critical for axonal growth, regeneration, and synaptic plasticity. STMN2 is a marker of neuronal injury and is implicated in neurodegenerative diseases.
