NDRG1 gene is a member of the N-myc downregulated gene family which belongs to the alpha/beta hydrolase superfamily. NDRG1 is a cytoplasmic protein involved in stress responses, hormone responses, cell growth, and differentiation. NDRG1 is necessary for p53-mediated caspase activation and apoptosis. Mutations in NDRG1 gene are a cause of Charcot-Marie-Tooth disease type 4D, and expression of this gene may be a prognostic indicator for several types of cancer. NDRG1 is a stress-responsive protein involved in hormone responses, cell growth, and differentiation. It acts as a tumor suppressor in many cell types.
