Generic protein structure example

Probable DNA dC->dU-editing enzyme APOBEC-3D is a protein that in humans is encoded by the APOBEC3D gene.[1][2]

This gene is a member of the cytidine deaminase gene family. It is one of seven related genes or pseudogenes found in a cluster, thought to result from gene duplication, on chromosome 22. Members of the cluster encode proteins that are structurally and functionally related to the C to U RNA-editing cytidine deaminase APOBEC1 and inhibit retroviruses, such as HIV, by deaminating cytosine residues in nascent retroviral cDNA.[2]

Function

APOBEC3D is one of the human APOBEC3 enzymes involved in restriction of HIV-1.[3][4] HIV-1 Vif counteracts APOBEC3D by recruiting ubiquitin-ligase machinery that leads to its polyubiquitination and proteasomal degradation in virus-producing cells.[3][4]
