NOD2

(Preusmjereno sa CARD15)

Protein 2 sa nukleotid-vezujućim domenom oligomerizacije (NOD2), znan i kao protein 15 sa domenom regrotacije kaspaze (CARD15) ili protein 1 upalne bolesti crijeva (IBD1), jest protein koji je kod ljudi kodiran genom NOD2 sa p kraka hromosoma 16.[5][6] NOD2 ima važnu ulogu u imunskom sistemu. Prepoznaje bakterijske molekule (peptidoglikane) i stimulira imunsku reakciju.[7]

NOD2 je unutarćelijski receptor prepoznavanja uzorka, koji je po strukturi sličan rezistentnim proteinima biljaka i prepoznaje molekule koji sadrže specifičnu strukturu zvanu muramil-dipeptid (MDP) koja se nalazi u određenim bakterijama.[8]

Aminokiselinska sekvenca

Dužina polipeptidnog lanca je 1.040 aminokiselina, a molekulska težina 115.283 Da.[9]

Struktura

uredi
 
Proteinski model NOD2 koji se sastoji od dva N-terminalna CARD domena (crvena) povezana preko spiralnog linkera (plava) sa centralnim NOD domenom (zelena). Na C-terminalu nalazi se LRR domen (cijan).[10]

C-terminalni dio proteina sadrži ponavljanje bogato leucinom, domen za koji je poznato da ima ulogu u interakcijama protein-protein. Srednji dio proteina karakterizira NOD-ov domen uključen u samooligomerizaciju proteina. N-terminalni dio sadrži dva CARD domena za koje se zna da imaju ulogu u apoptozi i NF-κB putevima aktivacije.[11]

Funkcija

uredi

Ovaj gen je član porodice NOD1/Apaf-1 (također poznate kao porodica NOD-liki receptori) i kodira protein sa dva domena regrutacije kaspaze ( CARD-a) i jedanaest ponavljanja bogatih leucinom (LRR). Protein se prvenstveno eksprimira u leukocitima periferne krvi. Ima ulogu u imunskom odgovoru, tako što prepoznaje bakterijske molekule koje posjeduju muramil-dipeptidni (MDP) dio i aktivira NF-κB protein.[9]

Klinički značaj

uredi

Mutacije ovog gena su povezane sa Crohnovom bolešću,[10] Blauovim sindromom, teškom plućnom sarkoidozom[12] i bolešću transplanta protiv domaćina.[13]

NOD2 gen je povezan sa upalnim bolestima kao što su upalna bolest crijeva/Crohnova bolest i Blauov sindrom.[14][15]

Interakcije

uredi

Pokazalo se da NOD2 reaguje sa NLRC4.[16][17]

Također se pokazalo da se NOD2 vezuje za MAVS, kao odgovor na tretman ssRNK ili virusne RNK i aktivira IFN odgovor. Ovo je prvi izvještaj da NOD2 djeluje kao receptor za prepoznavanje uzoraka za viruse.[18]
