MIA3/TANGO1 also known as Melanoma Inhibitory Activity 3 or Transport and Golgi Organization 1 is a protein with a molecular mass of approximately 190 kDa. This protein mainly expresses in the endoplasmic reticulum (ER). It plays an essential role in the secretory pathway by mediating the export of large molecules such as collagen from the ER to the Golgi apparatus. MIA3/TANGO1 acts as a scaffold organizing COPII vesicle coating components to facilitate the correct packaging and export of secretory proteins.
Biological function summary
MIA3/TANGO1 integrates into a larger ER export complex. This complex includes other proteins like cTAGE5 and Sec12 which assist in the proper assembly and budding of cargo-loaded vesicles. It maintains cellular homeostasis by ensuring cells correctly secrete ECM molecules such as collagen. Proper ECM molecule assembly and export are critical for maintaining tissue architecture particularly in connective tissues where collagen forms a substantial part of the structural matrix.
Pathways
MIA3/TANGO1 participates in the collagen biosynthesis and trafficking pathway. It actively interacts with proteins like cTAGE5 and Sec23 which are key components in the COPII vesicle formation. By influencing these pathways it affects the overall dynamics of the secretory machinery contributing to the accurate delivery of structural proteins necessary for cell structure integrity. MIA3/TANGO1's activity impacts the efficiency of the ER-to-Golgi transport an essential transition within the secretory pathway.
MIA3/TANGO1's dysfunction links to connective tissue disorders and certain forms of cancer. Mutations in MIA3/TANGO1 impact collagen secretion efficiency leading to conditions like Ehlers-Danlos syndrome a connective tissue disorder. Its interactions with proteins involved in these diseases such as HSP47 (a collagen-specific chaperone) further highlight its pathological relevance. Abnormal MIA3/TANGO1 function also associates with tumorigenesis as its role in ECM regulation could influence the tumor microenvironment impacting cancer progression.
