MCOLN1
Mukolipin-1 znan i kao TRPML1 (član 1 pčotporodice mukolipina, tranzijentnog potencijalnog receptorskog kationskog kanala) jest protein koji je kod ljudi kodiran genom MCOLN1 sa hromosoma 19.[5] Član je male porodice TRPML kanala, podgrupe velike porodice proteina TRP ionskih kanala.

Funkcija
urediTRPML1 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]
