Glikoprotein 130

Glikoprotein 130 (takođe poznat kao gp130, IL6ST, IL6-beta ili CD130) je transmembranski protein. On je osnivački član klase citokinskih receptora. On formira jednu podjedinicu tipa I citokinskih receptora u IL-6 receptorskoj familiji. On se često naziva zajedničkom gp130 podjedinicom, i važan je za signal transdukciju nakon interakcije sa citokinom. Kao i drugi citokinski receptori tipa I, gp130 poseduje WSXWS aminokiselinski motiv koji osigurava korektno proteinsko savijanje i vezivanje liganda. On interaguje sa Janus kinazom da bi izazvao intracelularni signal nakon interakcije receptora sa ligandom. Strukturno, gp130 se sastoji od pet fibronektin tip-III domena i jednog imunoglobulinu-sličnog C2-tipa domena na njegovom ekstracelularnom delu.[1][2]

Karakteristike уреди

Svi članovi IL-6 receptorske familije formiraju kompleks sa gp130 proteinom, i putem njega prenose signal. Na primer, IL-6 se veže za IL-6 receptor. Kompleks ova dva proteina se onda asocira sa gp130. Taj kompleks od 3 proteina se homodimerizuje da formira heksamerni kompleks koji može da proizvede nizvodne signale.[3] Postoje mnogi drugi proteini koji se asociraju sa gp130, kao što su kardiotrofin 1 (CT-1), inhibitorni faktor leukemije (LIF), cilijarni neurotrofni faktor (CNTF), onkostatin M (OSM), i IL-11.[4] Postoji takođe nekoliko drugih proteina koji imaju strukturnu sličnost sa gp130, sadrže WSXWS motiv i očuvane cisteinske ostatke. Članovi ove grupe su: LIF-R, OSM-R, i G-CSF-R.

Gubitak gp130 уреди

gp130 je važan deo mnogih različitih tipova signalnih kompleksa. Inaktivacija gp130 proteina je letalna kod miševa.[5] Homozigotni miševi nakon rođenja ispoljavaju brojne defekte, jedan od kojih je poremećeni razvoj ventrikularnih miokardijuma. Hematopoetski efekti obuhvataju redukovanje brojeva stem ćelija u slezini i jetri.

Prenos signala уреди

gp130 nema unutrašnju tirozin kinaznu aktivnost. Umesto toga, on je fosforilisan na tirozin ostacima nakon kompleksiranja sa drugim proteinima. Fosforilacija dovodi do asocijacije sa JAK/Tyk tirozin kinazama i STAT proteinskim transkripcionim faktorima[6] Specifično, STAT-3 se aktivira, što dovodi do aktivacije mnogih nizvodnih gena. Drugi putevi aktivacije su RAS i MAPK signalizacija.

Interakcije уреди

Za glikoprotein 130 je bilo pokazano interaguje sa TLE1,[7] SOCS3,[8] HER2/neu,[9] PTPN11,[8][10][11] Leukemijski inhibitorni faktor receptorom,[12][13] Grb2,[14] Janus kinaza 1[11][15][16] i SHC1.[17]
