Recombinant Human Muted protein

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The Muted protein also known as MUTED plays a role in the trafficking and sorting of proteins in vesicles. This small protein with an approximate molecular mass of 22 kDa mainly expresses in melanocytes but researchers have also observed it in other cell types. It functions closely with other proteins involved in the regulation of melanosome biology. The expression pattern of Muted suggests it has specific roles in pigmentation and possibly related cellular processes.

Biological function summary

Muted influences important cellular functions by forming part of the biogenesis of lysosome-related organelles complex-1 (BLOC-1). This complex which includes eight subunits is vital for the generation of lysosome-related organelles such as melanosomes and platelet-dense granules. Muted's role in the complex affects the specialized organelles essential for pigmentation and other related cellular processes. Without proper functioning of BLOC-1 various cellular activities reliant on functional organelles face impairment.

Pathways

Muted and other molecules participate in the endosomal-lysosomal pathway and the melanosome biogenesis pathway. These pathways are important for the formation of lysosome-related organelles. Alongside proteins like Pallidin and Cappuccino Muted influences the movement and formation of vesicles required for transporting cargos to their destination within cells. Proper coordination within these pathways ensures cellular components reach the right location influencing pigmentation and other cell-specific functions.

Muted's malfunction associates with conditions such as Hermansky-Pudlak syndrome and oculocutaneous albinism type 2. These disorders result from defects in the biogenesis of lysosome-related organelles. Muted and associated proteins like Melanophilin and Myosin Va guide the transport mechanisms impaired in these disease states leading to characteristic symptoms like hypopigmentation and bleeding disorders. Understanding the Muted protein helps in deciphering the molecular basis of these conditions and aids in the development of potential interventions.
