ExosomeExosome

The exosome complex (or PM/Scl complex, often just called the exosome) is a multi-protein complex capable of degrading various types of RNA (ribonucleic acid) molecules.

Function

Disease

Autoimmunity

The exosome complex is the target of autoantibodies in patients that suffer from various autoimmune diseases. These autoantibodies are mainly found in people that suffer from the PM/Scl overlap syndrome, an autoimmune disease. In these diseases, antibodies are mainly directed against two of the proteins of the complex, called PM/Scl-100 and PM/Scl-75.

Cancer treatment

The exosome has been shown to be inhibited by the antimetabolite fluorouracil, a drug used in the chemotherapy of cancer. It is one of the most successful drugs for treating solid tumors.

Relevance

Structural highlights

The core of the Exosom complex is made of a ring, which consisting of six RNases proteins (Rnase PH-like proteins).

This is a sample scene created with SAT to by Group, and another to make of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
