MCOLN1

Description

The MCOLN1 gene encodes mucolipin-1, a protein that plays a crucial role in regulating calcium signaling within cells. It is a transmembrane protein located in the lysosomal membrane, where it acts as a calcium channel. This channel controls the release of calcium ions from lysosomes into the cytoplasm, influencing various cellular processes, including lysosomal function, autophagy, and immune responses.

Associated Diseases

• Mucolipidosis type IV (MLIV): A rare, autosomal recessive disorder characterized by severe neurological impairments, skeletal abnormalities, and lysosomal storage disease. Mutations in MCOLN1 are the primary cause of MLIV.
• Other lysosomal storage disorders: While MLIV is the most prominent association, MCOLN1 mutations have been implicated in other lysosomal disorders, suggesting a broader role in maintaining lysosomal homeostasis.
• Neurodegenerative disorders: Studies have linked MCOLN1 to neurodegenerative conditions like Alzheimer‘s disease and Parkinson‘s disease, pointing to its potential involvement in neuronal calcium signaling and dysfunction.
• Immune system disorders: MCOLN1‘s role in immune cell function and calcium signaling suggests potential connections to immune system dysregulation and autoimmune disorders.

Did you know?

Mutations in MCOLN1 can lead to the accumulation of complex sugars within lysosomes, a hallmark of MLIV and other lysosomal storage disorders.
