APOBEC3DE is catalytically inactive due to a fixed Tyr320Cys substitution.
APOBEC3DE can form homo- and heterodimers with APOBEC3F and APOBEC3G.
APOBEC3DE suppresses APOBEC3F and APOBEC3G from HBV particles.
APOBEC3DE antagonizes the negative effects of APOBEC3F and APOBEC3G.
APOBEC3DE helps HBV to replicate.
