NR1B1 je gen sa proteinskim proizvodom i ima hromosomsku lokaciju 17q21.2. RARA kodira receptora jedarnog hormona, receptor retinojske kiseline, podtip alfa i sam je transkripcijski faktor. Postoje još dva podtipa RAR-a, beta i gama.[7][8]
Retinoidnu signalizaciju transduciraju članovi dvije porodice jedarnih receptora, receptor retinojske kiseline (RAR) i retinoidnui X-receptor (RXR), koji formiraju RXR/RAR heterodimere. U nedostatku liganda, DNK vezani RXR/RARA potiskuje transkripciju, regrutacijom korepresora NCOR1, SMRT (NCOR2), i histon-deacetilaze. Kada se ligand veže za kompleks, inducira konformacijsku promjenu koja omogućava regrutovanje koaktivatora, histon-acetiltransferaza i osnovnog transkripcijskog mehanizma.[9]
Kada se retinoična kiselina veže za RAR, oni pokreću transkripciju i omogućavaju ekspresiju njihovog gena.[10]
Klinički značaj
RA signalizacija je u korelacijama sa nekoliko signalnih puteva u ranom embrionskom razvoju. Prvo, učestvuje u formiranju embrionske osovine, koja uspostavlja simetriju u potomstvu. RA također utiče na nervnu diferencijaciju. regulacijom ekspresije proneurvnog indukcionog faktora meurogenina 2 (neurog2). RA utiče na kardiogenezu, jer ima posebnu ulogu u formiranju srčane pretkomore. RA također ima ulogu u razvoju pankreasa, bubrega, pluća i ekstremiteta.[10]
Translokacije koje uvijek uključuju preuređivanje gena RARA su kardinalna karakteristika akutne promijelocitne leukemije (APL; MIM 612376). Najčešća translokacija je t(15,17)(q21;q22), koja spaja gen RARA sa genom PML.[11]
Interakcije
Pokazalo se da receptor alfa retinojske kiseline reaguje sa:
Knock-out mice studies showed that a deletion in one of the copies of the RARA gene did not create any observable defect, while deletion of both copies shoes symptoms similar to that of Vitamin A deficiency. This proved that all 3 subtypes of RARs work redundantly.
