NDRG1 is a 394 amino acid cytoplasmic protein belonging to the NDRG family. It interacts with APO A-I and A-II and plays a role in HDL-mediated cholesterol transport, stress responses, hormone responses, cell growth and differentiation. Its defect causes Charcot-Marie-Tooth disease type 4D (CMT4D) that is characterized by reduced nerve conduction velocities, segmental demyelination and remyelination with onion bulb formations on nerve biopsy, slowly progressive distal muscle atrophy and weakness, absent deep tendon reflexes and hollow feet. NDRG1 plays a growth inhibitory role and serves as a marker of differentiation. It is expressed in placental membranes, prostate, kidney, small intestine, ovary tissues, colon and the cells that border the lumen.
