Funkcija[uredi | uredi izvor]

TRPML1 je protein od 65 kDa povezan sa mukolipidozom tipa IV. Njegova predviđena struktura uključuje šest transmembranskih domena, tranzijentni receptorski potencijal (TRP) domena kationskog kanala i pore unutrašnjeg kanala.^[6] Vjeruje se da TRPML1 kanališe ione željeza preko endosomne/lizozomne membrane u ćeliju i tako njegov kvar uzrokuje ćelijski nedostatak željeza.^[7] Važan je u funkciji lizosoma i igra ulogu u procesima kao što su promet vezikula, egzocitoza i autofagija.^[8]^[9]
