    The APOBEC3 (A3) proteins are host antiviral cellular proteins that hypermutate the viral genome of diverse viral families. In retroviruses, this process requires A3 packaging into viral particles1-4. The lentiviruses encode a protein Vif that antagonizes A3 family members by targeting them for degradation. Diversification of A3 allows host escape from Vif whereas adaptations in Vif enable…

    • Paper out today in the Accelerated Article Preview of @Nature reports the #cryoEM structure of APOBEC3G in complex with the #HIV protein Vif and co-factors. Fred Hutch's @memerman lab contributed the functional and evolutionary validation of the structure. https://t.co/10oistYEqy https://t.co/vU0wmJB1lb

    SPOP is the most mutated protein in prostate cancer. However, it is not fully understood how SPOP mutations drive cancer. Now, scientists at St. Jude Children’s Research Hospital report they have used cryo-electron microscopy (cryo-EM) to capture the first 3D structure of the entire SPOP assembly.
