strucutural modeling of enzyme. Residue F785 participates in a hydrophobic network between three transmembrane segments. Residue T618 is located in the cytoplasmic part of the molecule near the catalyitc site | Homo sapiens |

F785L | mutation associated with familial rapid-onset dystonia parkinsonism, leads to functionally altered, but active, Na+K+-pumps with reduced apparent affinity for cytoplasmic Na+. Defect in the interaction of the E1 form of enzyme with Na+, and the E1-E2 equilibrium is not displaced. K+ interaction at the external activating sites of E2P phosphoenzyme is normal. The affinity for ouabain is significantly reduced | Homo sapiens |
F785L/L786F | aromatic function of F785 is critical for Na+ and ouabain binding | Homo sapiens |
F785Y | aromatic function of F785 is critical for Na+ and ouabain binding | Homo sapiens |
T618M | mutation associated with familial rapid-onset dystonia parkinsonism, leads to functionally altered, but active, Na+K+-pumps with reduced apparent affinity for cytoplasmic Na+. The Na+-affinity is reduced because of displacement of the conformational equilibrium in favor of the K+-occluded E2 form. K+ interaction at the external activating sites of E2P phosphoenzyme is normal | Homo sapiens |
