Mucolipin-1 also known as TRPML1 (transient receptor potential cation channel, mucolipin subfamily, member 1) is a protein that in humans is encoded by the MCOLN1 gene.[5] It is a member of the small family of the TRPML channels, a subgroup of the large protein family of TRP ion channels.

TRPML1 is a 65 kDa protein associated with mucolipidosis type IV. Its predicted structure includes six transmembrane domains, a transient receptor potential (TRP) cation-channel domain, and an internal channel pore.[6] TRPML1 is believed to channel iron ions across the endosome/lysosome membrane into the cell and so its malfunction causes cellular iron deficiency.[7] It is important in lysosome function and plays a part in processes such as vesicular trafficking, exocytosis and autophagy.[8][9]
