Mucolipins 1-3 are ion channel proteins that belong to the transient receptor potential (TRP) superfamily of cation channels and are the major Ca2+-permeable channels on late endosomes and lysosomes (LEL). This entry represents the extracytosolic domain (ECD) which consists of two beta sheets and two extracytosolic helices that tetramerize into a ring that caps the extracytosolic side of the channel [1-5].
