Retikulon 4, znan i kao inhibitor izrastanja neurita ili Nogo, jest protein koji je kod ljudi kodiran genom RTN4 sa hromosoma 2.^[5]^[6]^[7] Identificiran je an kao inhibitor izrastanja neurita specifičnog za centralni nervni sistem. Tokom nervnog razvoja, Nogo se uglavnom eksprimira putem neurona i pruža inhibitorni signal za migraciju i klijanje endotelnih (vrh) ćelija CNS-a, čime se ograničava gustoća krvnih sudova.

Funkcija

Ovaj gen pripada porodici retikulonskih kodirajućih gena. Retikuloni su povezani s endoplazmatskim retikulumom i uključeni su u neuroendokrinu sekreciju ili u membranski promet u neuroendokrinim ćelijamama. Proizvod ovog gena je moćan inhibitor rasta neurita koji takođe može pomoći u blokiranju regeneracije centralnog nervnog sistema kod viših kičmenjaka. Identificirane su alternativno prerađene varijante transkripta izvedene iz diferencijalne prerade i upotrebe diferencijalnog promotora i kodiranja različitih izoformi.^[7] Postoje tri izoforme: Nogo A, B i C. Nogo- A ima dva poznata inhibitorna domena, uključujući amino-Nogo, na N-terminalu i Nogo-66, koji čini molekule vanćelijske petlje. I amino-Nogo i Nogo-66 su uključeni u inhibitorne odgovore, gdje je amino-Nogo jak inhibitor rasta neurita, a Nogo-66 uključen je u uništavanje konusa rasta.^[8]

Istraživanja sugeriraju da će blokiranje Nogo-A tokom oštećenja neurona (od bolesti kao što je multipla skleroza) pomoći u zaštiti ili obnavljanju oštećenih neurona.^[8]^[9] Istraživanje mehanizama djelovanja ovog proteina predstavlja veliki potencijal za liječenje autoimuno posredovanih demijelinizirajućih oboljenja i regeneracija povreda kičmene moždine. Također je utvrđeno da je ključni faktor u procesu u kojem fizička vježba poboljšava procese učenja i pamćenja u mozgu.^[10] Također se pokazalo da Nogo-A negativno regulira rast i popravak krvnih sudova nakon ishemijskog moždanog udara. Genetička delecija i blokada Nogo-A, posredovana antitijelima doveli su do poboljšane revaskularizacije i funkcionalnog oporavka u eksperimentalnom mišjem modelu moždanog udara.^[11]^[12]^[13] Moreover, vascular leakage, a major complication following stroke, was reduced following anti-Nogo-A antibody treatment.^[14]

Interakcije

Pokazalo se da retikulon 4 reaguje sa WWP1,^[15] BCL2-liki 1^[16] i Bcl-2.^[16]
