ADAMTS13
ADAMTS13 (eng. a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) — znan i kao von Willebrandov faktor cijepanja proteaze (VWFCP) — metaloproteazni enzim koji sadrži cink, a koja cijepa von Willebrandov factor (vWf), veliki protein uključen u zgrušavanje krvi. Izlučuje se u krv i razgrađuje velike multimere vWf, smanjujući njihovu aktivnost.[5]

Genetika
[uredi | uredi izvor]Gen ADAMTS13 mapiran je na hromosomu 9, sekvenca 9q34.[5]
Otkriće
[uredi | uredi izvor]Od 1982. godine bilo je poznato da je trombocita trombocitopenija purpura (TTP), jedna od mikroangiopatskih hemolitskih anemija (vidi dolje), u svom porodičnom obliku okarakterizirana prisustvom u plazmi neobično velikog multimernog von Willebrandov faktora (ULVWF).[5]
Godine 1994. pokazano je da se vWF cijepa između tirozina na položaju 1.605 i metionina na 1.606 enzimnom metaloproteazom u plazmi kada je bio izložen visokim razinama smicanja. U 1996., dvije su istraživačke grupe neovisno dodatno okarakterizirale ovaj enzim. U sljedeće dvije godine, iste dvije grupe pokazale su da je urođeni nedostatak cijepanja vWF proteazama povezan s stvaranjem trombocitnih mikrotrombova u malim krvnim žilama. Osim toga, izvijestili su da su IgG antitijela usmjerena protiv istog enzima, izazivajući TTP u većini slučajeva koji nisu porodični.[5]
Proteomika
[uredi | uredi izvor]Genomski, ADAMTS13 dijeli mnoga svojstva sa 19 članova porodice ADAMTS porodica, a sve njih karakterizira domen proteaze (dio koji obavla hidrolizu proteina), susjedni dezintegrinski domen i jedan ili više domena trombospondina. ADAMTS13 u stvari ima osam domena trombospondina. Nema hidrofobni transmembranski domen pa nije usidren u ćelijskoj membrani.[5]
Klinički značaj
[uredi | uredi izvor]Nedostatak ADAMTS13 prvobitno je otkriven u Upshaw-Schulmanovom sindromu, ponavljajućem porodičnom obliku trombocitne trombocitopenije purpure. Do tada se već sumnjalo da se TTP javlja i u autoimunskom obliku, zbog odgovora na plazmaferezu i karakterizacije IgG inhibitora. Od otkrića ADAMTS13, pokazalo se da su specifični epitopi na njegovoj površini meta inhibitornih antitijela.[5][7][8]
Nizak nivo ADAMTS13 je takođe povezan sa povećanim rizikom od arterijske tromboze,[9] uključujući infarkt miokarda[10] i cerebrovaskularnu bolest.[11][12]= 6 | pages = e0179258 | date = 2017 | pmid = 28591212 | doi = 10.1371/journal.pone.0179258
Konačno, budući da je dokazano da je veza između stenoza aortnog zaliska i angiodisplazije posljedica visokog smicnog naprezanja (Heydeov sindrom), prihvaćeno je da povećana izloženost vWf do ADAMTS13 zbog različitih razloga koji bi predisponirali krvarenje, uzrokujući povećanu degradaciju vWf. Ovaj fenomen karakterizira oblik von Willebrandove bolesti (tip 2a).[5]
