Mucolipin 1 Proteins and Enzymes

Mucolipin-1 (MCOLN1) is a 65kDa member of the TRPML channel family, which is a subgroup of the large protein family of TRP ion channels. Mucolipin 1 is thought to channel iron ions across the endosome/lysosome membrane into the cell, so defective MCOLN1 may cause cellular iron deficiency.

Defects in MCOLN1 are known to cause mucolipidosis type IV (MLIV), also known as sialolipidosis. MLIV is an autosomal recessive lysosomal storage disorder characterized by severe psychomotor retardation and ...
