Positive selection of primate TRIM5α identifies a critical species-specific retroviral restriction domain

SL Sawyer, LI Wu, M Emerman… - Proceedings of the …, 2005 - National Acad Sciences
Primate genomes encode a variety of innate immune strategies to defend themselves
against retroviruses. One of these, TRIM5α, can restrict diverse retroviruses in a species-specific …

[HTML][HTML] Ancient adaptive evolution of the primate antiviral DNA-editing enzyme APOBEC3G

SL Sawyer, M Emerman, HS Malik - PLoS biology, 2004 - journals.plos.org
Host genomes have adopted several strategies to curb the proliferation of transposable
elements and viruses. A recently discovered novel primate defense against retroviral infection …

High-throughput DNA sequencing errors are reduced by orders of magnitude using circle sequencing

…, R Andino, WH Press, SL Sawyer - Proceedings of the …, 2013 - National Acad Sciences
A major limitation of high-throughput DNA sequencing is the high rate of erroneous base
calls produced. For instance, Illumina sequencing machines produce errors at a rate of ∼0.1–1 …

Just 2% of SARS-CoV-2− positive individuals carry 90% of the virus circulating in communities

…, L Leinwand, R Parker, SL Sawyer - Proceedings of the …, 2021 - National Acad Sciences
We analyze data from the fall 2020 pandemic response efforts at the University of Colorado
Boulder, where more than 72,500 saliva samples were tested for severe acute respiratory …

[HTML][HTML] Discordant Evolution of the Adjacent Antiretroviral Genes TRIM22 and TRIM5 in Mammals

SL Sawyer, M Emerman, HS Malik - PLoS pathogens, 2007 - journals.plos.org
TRIM5α provides a cytoplasmic block to retroviral infection, and orthologs encoded by some
primates are active against HIV. Here, we present an evolutionary comparison of the TRIM5 …

[PDF][PDF] Species-specific deamidation of cGAS by herpes simplex virus UL37 protein facilitates viral replication

…, K Lee, GJ Seo, L Chen, AC Stabell, Z Xia, SL Sawyer… - Cell host & …, 2018 - cell.com
Herpes simplex virus 1 (HSV-1) establishes infections in humans and mice, but some non-human
primates exhibit resistance via unknown mechanisms. Innate immune recognition …

Two-stepping through time: mammals and viruses

NR Meyerson, SL Sawyer - Trends in microbiology, 2011 - cell.com
Recent studies have identified ancient virus genomes preserved as fossils within diverse
animal genomes. These fossils have led to the revelation that a broad range of mammalian …

[HTML][HTML] Dual host-virus arms races shape an essential housekeeping protein

…, J Abraham, H Choe, M Farzan, SL Sawyer - PLoS …, 2013 - journals.plos.org
Transferrin Receptor (TfR1) is the cell-surface receptor that regulates iron uptake into cells,
a process that is fundamental to life. However, TfR1 also facilitates the cellular entry of …

Filovirus receptor NPC1 contributes to species-specific patterns of ebolavirus susceptibility in bats

…, LF Wang, JH Kuhn, MA Müller, JM Dye, SL Sawyer… - Elife, 2015 - elifesciences.org
10.7554/eLife.11785.001 Biological factors that influence the host range and spillover of
