Funkcija[uredi | uredi izvor]

Istraživanja su otkrila da je ovaj protein, zajedno sa ostalim LRRC8 proteinima LRRC8A, LRRC8B, LRRC8C i LRRC8E, podjedinica heteromernog proteina zapreminski reguliranog anionskog kanala.^[7] Ti kanali (VRAC) ključni su za regulaciju veličine ćelije transportom hloridnih iona i raznih organskih osmolita, poput taurina ili glutamata, kroz plazmamembranu,^[8] i to nije jedina funkcija na koju su ovi ionski kanali povezani.

Dok je LRRC8D jedan od mnogih proteina koji mogu biti dio VRAC-a, on je zapravo jedna od najvažnijih podjedinica za sposobnost kanala da funkcionira; drugi važan protein je LRRC8A.^[9]^[10] Međutim, iako se zna da je neophodan za specifičnu VRAC funkciju, druge studije su otkrile da to nije dovoljno za cijeli raspon uobičajenih aktivnosti VRAC-a.^[11] Tu dolaze drugi proteini LRRC8, jer različit sastav ovih podjedinica utiče na opseg specifičnosti za VRAC-eve.^[12]^[13]

Pored svoje uloge u VRAC, porodica proteina LRRC8 je takođe povezana sa agamaglobulinemijom-5.^[14]
