Struktura[uredi | uredi izvor]

Analiza sekvence GBP2 pokazala je prisustvo RNK-vezujućeg domena koji se sastoji od tri motiva prepoznavanja RNK (RRM) i SR domena. Amino terminal GBp2 dijeli četiri motiva ponavljanja Arg-Gly-Gly (RGG) i devet serinskih ostataka u kontekstu arginin/serinskih motiva.^[9]

SR domen GBP2 je mjesto fosforilacija za SR specifičnu protein-kinazu SRPK (sky1) koja usmjerava jedarnu lokalizaciju GBP2.

Svinjski GBP2 ima veliku sličnost u pogledu N-terminala koji je globulski domen i sadrži funkciju GTPaza. Međutim, C-terminal ima spiralni domen koji je manje konzerviran.^[10]

Funkcija[uredi | uredi izvor]

Interferoni su citokini koji imaju antivirusne efekte i inhibiraju ćelijsku proliferaciju tumora. Indukuju veliki broj gena u svojim ciljnim ćelijama, uključujući i one koji kodiraju gvanilat-vezujući protein (GBP). GBP se odlikuju sposobnošću da specifično vežu guaninske nukleotide (GMP, GDP i GTP). Protein kodiran ovim genom je GTPaza koja pretvara GTP u GDP i GMP.^[6] Osim toga, GBP2 gen može biti veza između površinskih ćelijskih receptore i unutarćelijskih efektora koji mogu prenijeti vanćelijske informacije u ćelije, kao i unutarćelijski signalni transdukcijski protein.^[11]

Studija na goveđem genu GBP2 pokazala je važnost GBP2 u regulaciji proliferacije ćelija i otpornosti na infekciju patogenom, kao što je Izlaganje antivirusnoj aktivnosti protiv virusa gripe.^[12]

GPB2 promovira oksidativno ubijanje i isporučuje antimikrobne peptide u autofagolizosom, pružajući široku zaštitu domaćina od različitih klasa patogena. Tokom virusne infekcije, porodica GBP (GBP1, GBP2 i GBP5) ima vitalnu ulogu u aktiviranju kanonskog i nekanonskog inflamasoma na odgovor na infekciju patogenom putem Chlamydia muridarum.^[13]

Lokalizacija[uredi | uredi izvor]

Gen GBP2 nalazi se u različitim odjeljcima u ćeliji: jedro, citosol i citoskelet, a također se dimer GBP2-GBP5 nalazi u Golgijevom aparatu.^[14]

Osim toga, za regulaciju unutarćelijske lokalizacije i membranske asocijacije GBP2 potrebna je i izoprenilacija.^[15]

Aktivacija[uredi | uredi izvor]

Mišji gen GBP2 nije samo visoko aktiviran interferon-gama tokom aktivacije makrofaga, već i stimulacijom Tol-likih receptore, faktora nekroze tumora (TNF) i interleukina-1 beta.^[16]

Ekspresija[uredi | uredi izvor]

Nakon stimulacije interferonom gama, mišji GPB2 eksprimira se u urođenim i prilagodljivim imunskim ćelijama.^[12]

Interakcija[uredi | uredi izvor]

Gen GBP2 može komunicirati sa RNK, preko domena RRM1 i RRM2. RRM2 domen može prepoznati osnovni motiv GGUC prisutan u RNK. Osim toga, identificiran je novi tip RRM domena koji može komunicirati sa kompleksom THO/TREX.^[17]

Gen GBp2 može surađivati sa TREX (transkripcija-eksport) kompleksom; multimerni kompleks ima različite transkripcijske i eksportne faktore kao što su Yra1 i Sub2.^[17]

Klinički značaj[uredi | uredi izvor]

Genska mutacija[uredi | uredi izvor]

Kod pacijenata s migrenom identificirana je misens mutacija GBP2 (A907G). U prvom koraku može dovesti do vazomotorne disfunkcije, a zatim do glavobolje.^[11]

Rak dojke[uredi | uredi izvor]

GBP2 se smatra kontrolnim faktorom za proliferaciju i širenje u tumorskoj ćeliji. Visoka ekspresija GBP2 povezana je s boljom dijagnozom raka dojke. P53 može regulirati GBP2 i imati esencijalnu ulogu u razvoju tumora, inhibicijom metaloproteinaze MM9 kao i NF-Kappa B i proteina Rac.^[18]

Nivo transkripcije GBP2 također je reguliran i putem dva faktora transkripcije STAT1 i IRF1. Ekspresija GBP2 ima jaku korelaciju sa metagenom T-ćelija što se čini povezanom sa infiltracijom T-ćelija u rak dojke.^[18]

Međutim, nedavna studija je pokazala da GBP2 može regulirati protein 1 (Drp1) povezan s dinaminom, kako bi blokirao translokaciju Drp1 u mitohondrije, što dovodi do slabljenja Drp1 ovisne mitohondrijske fisije i također invazija ćelija raka dojke.^[19]
