Struktura

Protein NLRC4 je visoko konzeran među vrstama sisara. Ima homologiju sa Ced4 proteinom C. elegans. Sadrži N-terminalni CARD domen, centralni nukleotidni vezujući domen/NACHT domen i C-terminalno [[leuxcin-bogatoponavljanje bogato ponavljanje (LRR ) domena. Pripada porodici NLR proteina koja uključuje koaktivator transkripcije CIITA i kanonski inflamasomski protein NLRP3. Skraćeni mišji NLRC4 bio je prvi član ove porodice čija je kristalna struktura riješena.^[7]

Funkcija

NLRC4 je najbolje povezan sa pokretanjem formiranja inflamasoma. Za razliku od NLRP3, određene funkcije NLRC4 zavisne od inflamasoma mogu se obavljati nezavisno od skele inflamasoma ASC. Ljudski Ced4 homolozi uključuju APAF1, NOD1 (CARD4) i NOD2 (CARD15). Ovi proteini imaju najmanje 1 N-terminalni CARD domen, praćen centralno lociranim domenom za vezivanje nukleotida (NBD ili NACHT) i C-terminalnim regulatornim domenom, koji se nalazi samo kod sisara, a sadrži ili WD40 ponavljanje ili ponavljanja bogata leucinom (LRR-ove). CARD12 je član porodice Ced4 i može izazvati apoptozu.^[6]

Interakcije

Pokazalo se da NLRC4 reaguje sa NAIP-om (postoji jedan ljudski NAIP, ali miševi eksprimiraju najmanje 4 različita NAIP proteina). Interakcija NAIP/NLRC4 može odrediti specifičnost liganda.^[8] Aktivnost inflamasoma ovisna o NLRC4 aktivira CASP1.^[9] Pod određenim okolnostima, NLRC4 i NLRP3 mogu zauzeti isti kompleks inflamasoma.^[10]

Klinički značaj

Ljudi koji imaju aktivirajuće mutacije u NLRC4 mogu razviti autoupalni sindrom karakteriziran akutnom temperaturom, hepatitisom, vrlo visokim serumskim feritinom i drugim karakteristikama koje upućuju na Sindrom aktivacije makrofaga (MAS) . Neki pacijenti su također razvili potencijalno po život opasan enterokolitis koji je nestajao u ranom djetinjstvu.^[11]^[12] Kod ovih pacijenata, pronađeno je hronično i izvanredno povišenje serumskog IL-18, za razliku od pacijenata sa mutacijama NLRP3 koji razvijaju kriopirinu pridruženie periodične sindrome.^[11] Velika japanska porodica imala je mnogo blažu bolest povezanu sa urtikarijom izazvanom hladnoćom koju je uzrokovala dominantno naslijeđena mutacija NLRC4.^[13]
