For many, “DNA mimic protein” (DMP) remains an unfamiliar term. The key feature of these proteins is their DNA-like shape and charge distribution, and they affect the activity of DNA-binding proteins by occupying their DNA-binding domains. Functionally, DMPs regulate mechanisms such as gene expression, restriction, and DNA repair as well as the nucleosome package. Although a few DMPs, such as phage uracil DNA glycosylase inhibitor (UGI) and overcome classical restriction (Ocr), were reported about 20 years ago, only a small number of DMPs have been studied to date. In 2014, we reviewed the functional and structural features of 16 DMPs that were known at the time. Now, seven new DMPs, namely anti-CRISPR suppressors AcrF2, AcrF10 and AcrIIA4, human immunodeficiency virus essential factor VPR, multi-functional inhibitor anti-restriction nuclease (Arn), translational regulator AbbA, and putative Z-DNA mimic MBD3, have been reported. In addition, further study of two previously known DMPs, DMP19 and SAUGI, increased our knowledge of their importance and function. Here, we discuss these updated results and address how several characteristics of the structure/sequence of DMPs (e.g. the DNA-like charge distribution and structural D/E-rich repeats) might someday be used to identify new DMPs using bioinformatic approach.
