RAR-beta
Receptor retinoidne kiseline beta (RAR-beta), znan i kao NR1B2 (član 2 B grupe potporodice 1 jedarnog receptora) je jedarni receptor jest protein koji je kod ljudi kodiran genom RARB sa hromosoma 3.[5][6]

Funkcija
[uredi | uredi izvor]Ovaj gen kodira beta receptor retinoidne kiseline, član superfamilije receptora za hormone štitnjače, regulatora jedarne transkripcije. Ovaj receptor nalazi se u citoplazmi i u subjedarnim odjeljcima. Veže retinoidnu kiselinu, biološki aktivni oblik vitamina A koji posreduje ćelijsku signalizaciju u morfogenezi embriona, rastu i diferencijaciji ćelija. Smatra se da ovaj protein ograničava rast mnogih tipova ćelija regulacijom ćelijskoj diferencijaciji i ekspresije gena. Gen je prvi put identificiran u hepatćelijskom karcinomu gdje se nalazi na boku mjesta integracije virusa hepatitisa B. Deregulacija ovog gena je također otkrivena u preneoplazijskim lezijama karcinoma grlića materice.[7] Gen eksprimira najmanje dvije varijante transkripta; opisan je još jedan transkript, ali nije utvrđena njegova puna dužina.[5]
Epigenetika
[uredi | uredi izvor]Uočeno je da je beta aberantni promotor receptora retinoidne kiseline hipermetilacije DNK povezan sa pojavom/progresijom raka. Zaista, ovaj neprikladan epigenetički fenomen je uočen kod žena zahvaćenih karcinomom skvamoznih ćelija vulve nastao je iz vulvinnog lichen sclerosus.[8] Metilacija beta promotora receptora retinoične kiseline može biti marker rizika od raka kod pacijenata oboljelih od ove bolesti.[8]
Interakcije
[uredi | uredi izvor]Pokazalo se da receptor beta receptora retinoidne kiseline reaguje sa NR4A2.[9]
