abstract = {The APOBEC3 (A3) family of cytidine deaminases plays a
vital role for innate defense against retroviruses.
Lentiviruses such as HIV-1 evolved the Vif protein that
triggers A3 protein degradation. There are seven A3
proteins, A3A-A3H, found in humans. All A3 proteins can
deaminate cytidines to uridines in single-stranded DNA
(ssDNA), generated during viral reverse transcription. A3
proteins have either one or two cytidine deaminase domains
(CD). The CDs coordinate a zinc ion, and their amino acid
specificity classifies the A3s into A3Z1, A3Z2, and A3Z3. A3
proteins occur as monomers, dimers, and large oligomeric
complexes. Studies on the nature of A3 oligomerization, as
well as the mode of interaction of A3s with RNA and ssDNA
are partially controversial. High-resolution structures of
the catalytic CD2 of A3G and A3F as well as of the single CD
proteins A3A and A3C have been published recently. The NMR
and X-ray crystal structures show globular proteins with six
α-helices and five β sheets arranged in a characteristic
motif (α1-β1-β2/2'-α2-β3-α3-β4-α4-β5-α5-α6).
However, the detailed arrangement and extension of
individual structure elements and their relevance for A3
complex formation and activity remains a matter of debate
and will be highlighted in this review.},
