OGFr
| edit |
Receptor opioidnog faktora rasta, OGFr ili ζ-opioidni receptor, je protein koji je kod čoveka kodiran OGFR genom.[1][2] On je receptor opioidnog faktora rasta (OGF), takođe poznatog kao Met-enkefalin. To je endogeni ligand ovog receptora. OGFr je originalno bio otkriven i nazvan kao novi opioidni receptor zeta (ζ). Međutim naknadno je utvrđeno da on ima neznatnu homologiju sekvence sa drugim opioidnim receptorima, i da ima veoma različitu funkciju.

Funkcija
urediPrirodna funkcija ovog receptora je regulacija rasta tkiva,[3][4][5][6] i bilo je pokazano da je važan u embrionskom razvoju,[7] zarastanju rana,[8] i za pojedine tipove raka.[9][10][11][12]
OGF je negativni regulator ćelijske proliferacije i organizacije tkiva u nizu procesa. Utvrđeno je da je nevezani receptor lokalizovan na spoljašnjosti jedra, gde on vezuje OGF i naknadno biva translociran u jedro. Kodirajuća sekvenca ovog gena sadrži polimorfni region sa 60 nukleotidnim tandemom nesavršenih ponavljajućih jedinica. Iranskripti koji sadrže između nula i osam ponavljajućih jedinica su nađeni.[1]
Terapeutske primena
urediPovišeno izražavanje OGFr-a i konsekventna stimulacija OGF-OGFr sistema su važni za antiproliferativne efekte imidazohinolinskih lekova kao što su imikuimod i rezikuimod, koji su modifikatori imunskog sistema sa potentnim antivirusnim i antitumorskim dejstvom. Oni se koriste kao topikalni kremovi za lečenje raka kože i bradavica.[13]
