TL;DR

Recent studies on how endogenous retrovirus- and other LTR retrotransposon-derived proteins and peptides contribute to human health and disease across three major domains are summarized.

Abstract

LTR retrotransposons, including endogenous retroviruses (ERVs), constitute approximately 9% of the human genome and represent remnants of ancient mobile genetic elements. Although most of these sequences have accumulated truncations and mutations and have long been regarded as genomic relics, accumulating evidence indicates that ERV- and other LTR retrotransposon-derived proteins and peptides are involved in various diseases and may serve as possible therapeutic targets. In this review, we summarize recent studies on how these proteins and peptides contribute to human health and disease across three major domains: neurological disorders, oncogenesis, and host defense. Continued advances in nucleotide sequencing technologies and proteomics are expected to further expand our understanding of the biological and pathological roles of endogenous retrovirus- and other LTR retrotransposon-derived proteins and peptides.

Structural Insights into Endogenous Retroviruses: Evolution and Co-Opted Functions

Endogenous retroviruses (ERVs) are the molecular remnants of ancient retroviral infections and constitute a substantial fraction of many vertebrate genomes. Although most ERV loci have lost coding capacity and are epigenetically silenced, some remain biologically relevant because they have been co-opted for host physio...

Co-option of retroviral genes: diversity and evolution in vertebrates.

Endogenous retroviruses (ERVs) are remnants of retroviral sequences that integrated into the host germline genome and are inherited across generations. Occasionally, the protein-coding genes within ERVs have been co-opted as host genes and contribute to diverse biological processes. In early studies, the identified ERV...

Direct cell-to-cell transmission of retrotransposons.

Transposable elements are abundant in host genomes but are generally considered to be confined to the cell in which they are expressed, with the notable exception of endogenous retroviruses. Here, we identify a group of long terminal repeat (LTR) retrotransposons that infect the germline from somatic cells within the D...

Discovery and engineering of avian R2 retrotransposons for all-RNA-mediated targeted DNA integration in human cells.

This work searched avian genomes, identified 159 avian R2 retrotransposons and characterized conserved/nonconserved sequence features in their proteins and untranslated region elements, which expands the avian R2 resource and provides additional tools for all-RNA-mediated genome editing.

Retrotransposon-based mechanisms for transgene addition to the human genome.

When human disease arises from a loss of function caused by diverse mutant alleles of the same gene, the patient population could be best served by a clinical therapy that achieves genome safe-harbor supplementation with a functional transgene. Until recently, transgene delivery strategies have shared the disadvantages...
