Struktura uredi

Gen uredi

Gen PARK7, također poznat kao DJ-1, kodira protein iz porodice peptidaza C56. Ljudski gen PARK7 ima osam egzona i nalazi se na hromozomskom pojasu 1p36.23.[5]

Protein uredi

Ljudska proteinska deglikaza DJ-1 je veličine 20 kDa i sastoji se od 189 aminokiselina sa ukupno sedam β-lanaca i devet α-heliksa i prisutna je kao dimer.[7][8][9] Proteinske strukture ljudskog proteina DJ-1, šaperona Hsp31Escherichia coli, YhbO i YajL i proteaze Archaea evolucijski su konzervirane.[10]

Funkcija uredi

U oksidativnom stanju, protein deglikaza DJ-1 inhibira agregaciju α-sinukleina putem svoje prateće aktivnosti,[11][12] funkcionifajući na taj način kao redoks-senzitivni šaperon i kao senzor za oksidativnog stresa. U skladu s tim, DJ-1 očigledno štiti neurone od oksidativnog stresa i ćelijske smrti.[5] Paralelno, protein DJ-1 djeluje kao pozitivan regulator transkripcije zavisne od androgenoreceptorski ovisne transkripcije. DJ-1 se eksprimira u neurvmojoj retini, mrežnjsčnom pigmentnom sloju i njenom epitelu kod sisara, gdje ima neuroprotektivnu ulogu protiv oksidativnog stresa i u fiziološkim i u patološkim stanjima.[13][14]

Pokazalo se da pirolokvnolin-kvinon (PQQ) smanjuje samooksidaciju DJ-1 proteina, što je rani korak u nastanku nekih oblika Parkinsonove bolesti.[15]

Pokazalo se da funkcionalni DJ-1 protein veže metale i štiti od citotoksičnosti izazvane metalima bakar i živa.[16]

Klinički značaj uredi

Defekti ovog gena uzrok su autosomno recesivnog ranog početka Parkinsonova bolest 7.[5][17]
