HADHA
Mitohondrijska podjednica alfa trifunkcijskog enzima znana i kao podjedinica alfa hidroksiacil-CoA dehidrogenaze/3-ketoacil-CoA tiolaze/enoil-CoA hidrataze alfa (trifunkcijski protein) jest enzim koji je kod ljudi kodiran genom HADHA sa hromosoma 2. Mutacije u HADHA su povezane sa nedostatkom trifunkcijskog proteina ili nedostatkom dugolančane 3-hidroksacil-koenzim A dehidrogenaze.[5]

Struktura[uredi | uredi izvor]
HADHA je protein od 82,9 kDa koji se sastoji od 763 aminokiseline.[7][8]
Mitohondrijski membranski vezani heterokompleks sastoji se od početiri alfa i beta podjedinice, pri čemu alfa podjedinica katalizira aktivnosti 3-hidroksiacil-CoA dehidrogenaze i enoil-CoA hidrataze. Geni alfa i beta podjedinica mitohondrijskog trifunkcijskog proteina nalaze se jedni uz druge u ljudskom genomu u orijentaciji glava-glava.[5]
Funkcija[uredi | uredi izvor]
Ovaj gen kodira alfa podjedinicu mitohondrijskog trifunkcijskog proteina, koji katalizira posljednja tri koraka mitohondrijske beta-oksidacije dugolančanih masnih kiselina.[5] Enzim pretvara srednje- i dugolančane spojeve 2-enoil-CoA u sljedeće 3-ketoacil-CoA kada je prisutan isključivo NAD i acetil-CoA , kada su prisutni NAD i CoASH .[9] Alfa podjedinica katalizira ovu reakciju i vezana je za HADHB, koji katalizira posljednji korak reakcije.[10]
Klinički značaj[uredi | uredi izvor]
Mutacije ovog gena rezultiraju nedostatkom trifunkcijskog proteina ili nedostatkom dugolančane 3-hidroksiacil-koenzim A dehidrogenaze.[5]
Najčešći oblik mutacije je G1528C, u kojem se guanin na 1528. poziciji mijenja u citozin. Mutacija gena stvara nedostatak proteina koji je povezan sa poremećenom oksidacijom dugolančanih masnih kiselina, što može dovesti do iznenadne smrti novorođenčeta.[11] Kliničke manifestacije ovog nedostatka mogu biti miopatija, kardiomiopatija, epizode koma i hipoglikemija.[12] Nedostatak dugolančane L-3-hidroksiacil-koenzim dehidrogenaze povezan je s nekim poremećajima specifičnim za trudnoću, uključujući preeklampsiju, HELLP sindrom (hemoliza, povišeni enzimi jetre, niske razine trombocita), hyperemesis gravidarum, akutno masnu jetru u trudnoći i infarkt placente na njenom majčinskom dnu.[13][14] Pored toga, to je povezano sa bolešću akutno masna jetra u trudnoći (AFLP).[15]
Iz kliničke perspektive, HADHA bi takođe mogao biti koristan marker za predviđanje otpornosti na određene tipove hemoterapije kod pacijenata sa rakom pluća.[16]
Interakcije[uredi | uredi izvor]
Pokazalo se da HADHA ima 142 binarne interakcije protein-protein uključujući 117 kokompleksnih interakcija. Čini se da je HADHA u interakciji sa GABARAP, MAP1LC3B, TRAF6, GABARAPL2, GABARAPL1, GAST, BCAR3, EPB41, TNFRSF1A, HLA-B, NFKB2, MAP3K1, IKBKE, PRKAB1, RIPK3, CD74, NR4A1, cdsA, mtaD, ATXN2L, ABCF2 i MAPK3.[17]
