Funkcija
[uredi | uredi izvor]Protein koji je kodiran ovim genom pripada porodici P-tipa kationskog transporta ATPaza i potporodice Na+/K+-ATPaza. Na+/K+ -ATPaza je integralni membranski protein, odgovoran za uspostavljanje i održavanje elektrohemijskog gradijenta Na i K iona preko plazmatske membrane. Ovi gradijenti su neophodni za osmoregulaciju, za natrijev – pregnuti transport različitih organskih i neorganskih molekula, te za električnu ekscitabilnost živaca i mišića. Ovaj enzim sastoji se od dvije podjedinice, velike katalitske podjedinice (alfa) i manje glikoproteinske podjedinice (beta). Katalitska podjedinica Na+ /K+ -ATPaza kodirana je sa više gena. Ovaj gen kodira podjedinicu alfa-3.[6]
Klinički značaj
[uredi | uredi izvor]Poznato je da varijante gena ATP1A3 koje uzrokuju bolest izazivaju razne poremećaje pokreta i epilepsije.[7] Poznata pridružena stanja uključuju razne sindrome:
1) Naizmjenična hemiplegija djetinjstva (AHC)
2) Brzonastaljuća distonija-parkinsonizam (RDP, poznat i kao DYT12)
3) Cerebelarne ataksija, arefleksija, pes cavus, optička atrofija i senzorineuralni gubitak sluha (CAPOS /CAOS sindrom)
4) Razvojna i epilepsijska encefalopatija
5) Paroksizamska slabost i encefalopatija izazvana vrućicom (FIPWE)
6) Ponavljajuće epizode cerebralne ataksije (RECA)
7) Vrlo rana shizofrenija.[8]
Kod miševa su mutacije ovog gena povezane sa epilepsijom. Manipuliranjem ovog gena u potomstvu takvih miševa epilepsija se može izbjeći.[9]
