6YXE - PubMed Abstract:
Members of the TRIM protein family have been shown to inhibit a range of viral infections. Recently, TRIM69 was identified as a potent inhibitor of Vesicular stomatitis Indiana virus infection, with its inhibition being dependent upon multimerization. Using SEC-MALLS analysis, it is demonstrated that the assembly of TRIM69 is mediated through the RING domain and not the Bbox domain as has been shown for other TRIM proteins. Using X-ray crystallography, the structure of the TRIM69 RING domain has been determined to a resolution of 2.1 Å, the oligomerization interface has been identified and regions outside the four-helix bundle have been observed to form interactions that are likely to support assembly.
