VCP and nervous system disorder: At least six different ER morphology regulators have been demonstrated to be involved in neurological disorders—including Valosin-containing protein (VCP), Atlastin-1 (ATL1), Spastin (SPAST), Reticulon 2 (RTN2), Receptor expression enhancing protein 1 (REEP1) and RAB10—suggesting a critical role of ER formation in neuronal activity and function.
