Disease

AT1A1_HUMAN Autosomal dominant Charcot-Marie-Tooth disease type 2DD;Primary hypomagnesemia-refractory seizures-intellectual disability syndrome. The disease is caused by variants affecting the gene represented in this entry. The disease is caused by variants affecting the gene represented in this entry.

Function

AT1A1_HUMAN This is the catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of sodium and potassium ions across the plasma membrane. This action creates the electrochemical gradient of sodium and potassium ions, providing the energy for active transport of various nutrients (PubMed:29499166, PubMed:30388404). Could also be part of an osmosensory signaling pathway that senses body-fluid sodium levels and controls salt intake behavior as well as voluntary water intake to regulate sodium homeostasis (By similarity).[UniProtKB:Q8VDN2]^[1] ^[2]
