• PubMed Abstract: 
  

  A study recently published in Hepatology Communications provided insights into a variant of MTARC1 protein, which conveys protection against liver disease. Here, we report a crystal structure of the variant protein at near-atomic resolution and compare it to the structure of the wildtype protein.
