Funkcija

uredi

Kako mu je naznačeno imenom, CXXC5 ima ulogu transkripcijskog faktora u ćelijskom jedru , te sudjeluje u mijelopoezi, endotelnoj diferencijaciji, stvaranju krvnih sudova i diferencijaciji oligodendrocita.[7][10][11]

CXXC5 je također okarakteriziran kao regulator negativne povratne sprege Wnt/β-kateninskog signalnog puta koji funkcionira direktnom interakcijom s neuređenim (Dvl) proteinom u citosolu.[6][10][12][13][14] Citosolna prekomjerna ekspresija CXXC5 izazvana je zbog nekoliko patofizioloških stanja, kao što su osteoporoza, alopecija, starenje ploče za rast, kožne rane i obnavljanje potisnute signalizacije Wnt/β-katenina, blokadom njegove funkcije vezivanja Dvl pogoršavajući patološke značajke primijećene kod miševa a genotipCxxc5 –/–.[10][13][14][15] Ovi rezultati ukazuju da bi vezivanje Dvl s citosolnim CXXC5 moglo biti meta za razvoj sredstava za liječenje alopecije, akutnih rana i niskog rasta u djetinjstvu i adolescenciji, koji pokazuju potisnutu signalizaciju Wnt/β-katenina citosolnom prekomjernom ekspresijom CXXC5 odgovornih ćelija tkiva.[12][14][15] The CXXC5-Dvl Interakcija protein-protein (PPI) kao meta za razvoj agenasa kod opadanja kose ili akutne rane također je potvrđena konstrukcijom i ispitivanjem funkcije PTD-DBM, peptida koji inhibira CXXC5-Dvl PPIl.[12][14]

Pobgoršanje abnormalnosti pomoću CXXC5-Dvl PPI inhibitora pripisuje se obnavljanju oštećenih tkiva aktiviranjem matičnih ćelija putem restorativne aktivacije potisnute signalizacije Wnt/β-katenina i njegovih ciljnih gena koji uključuju regeneraciju.
