Gag proteins encoded by endogenous retroviruses are required for zebrafish development

ABSTRACT: Transposable elements (TEs) make up the bulk of eukaryotic genomes and examples abound of TE-derived sequences repurposed for organismal function. The process by which TEs become coopted remains obscure because most cases involve ancient, transpositionally inactive elements. Reports of active TEs serving beneficial functions are scarce and often contentious due to difficulties in manipulating repetitive sequences. Here we show that recently active TEs in zebrafish encode products critical for embryonic development. Knockdown and rescue experiments demonstrate that the endogenous retrovirus family BHIKHARI-1 (Bik-1) encodes a Gag protein essential for mesoderm development. Mechanistically, Bik-1 Gag associates with the cell membrane and its ectopic expression in chicken embryos alters cell migration. Similarly, depletion of BHIKHARI-2 Gag, a relative of Bik-1, causes defects in neural crest development in zebrafish. We propose an “addiction” model to explain how active TEs can be integrated into conserved developmental processes.

CLIP-seq analysis of WT and Gag chimera HIV-1 virions 3

Project description:To investigate how the major HIV-1 structural protein Gag packages viral genomes efficiently, we replaced the NC domain of Gag with RNA binding domains from heterologous cellular RNA binding proteins to generate Gag chimeras. We hypothesize that the Gag chimeras that preferentially bind to purine-rich RNA sequences will package viral genomes efficiently. We performed CLIP-seq to identify the RNA sequences bound by WT Gag and Gag chimeras in cells, at the plasma membrane, and in virions.

RNA Sequencing of Novel HIV RNA TAR-gag and Host Genome of EVs from HIV-1 Infected Cells

Project description:We performed a 3' RACE of a novel HIV RNA TAR-gag in order to determine the sequence of the RNA at the 3' end. Our data had shown that TAR-gag was potentially a noncoding RNA and our hypothesis was that TAR-gag ended somewhere prior to the end of the gag region of the HIV genome. The 3' RACE experiment showed that TAR-gag actually consists of four different RNA clusters, the longest of which ends at 615 bases from the transcription start site; this is in the middle of the p17 region of the gag gene. In addition, we sequenced all host RNAs in the EVs.

Determination of Gag stoichiometry for different production platforms by PRM analysis

Project description:In this work we established an analytical method of characterization for the Gag protein core and clarify the current variability of Gag stoichiometry in HIV-1 VLPs depending on the cell-based production platform, directly determining the number of Gag molecules per VLP in each case. Three Gag peptides have been validated to quantify the number of monomers using parallel reaction monitoring (PRM)

Comparative analysis of retroviral Gag-host cell interactions in the nucleus

Project description:Retroviruses exploit a variety of host proteins to assemble and release virions from infected cells. To date, most studies that examined possible interacting partners of retroviral Gag proteins focused on host proteins that localize primarily to the cytoplasm or plasma membrane. Given the recent findings that several full-length Gag proteins localize to the nucleus, identifying the Gag-nuclear interactome has high potential for novel findings that reveal previously unknown host processes. This dataset contains results from a mass spectrometry approach using affinity-tagged (His6) HIV-1 and RSV Gag proteins mixed with nuclear extracts, and identifies potential binding partners of HIV-1 and RSV Gag involved in several nuclear processes, including transcription, splicing, RNA modification, and chromatin structure. Although a subset of host proteins interacted with both Gag proteins, there were also unique host proteins belonging to each interactome dataset. These results provide a strong premise for future functional studies to investigate roles for these nuclear host factors that may have shared functions in the biology of both retroviruses, as well as functions specific to RSV and HIV-1, given their distinctive hosts and molecular pathology.

CpG dinucleotides introduced into gag can inhibit HIV-1 gene expression by modulating pre-mRNA splicing

Project description:Progressively longer regions of the gag gene sequence in HIV-1 were codon-optimized, which introduced 11, 18 or 26 CpGs (CM22-165: codon-optimized gag from nucleotide 22 to 165, adding 11 CpGs; CM22-261: 18 CpGs; CM22-378: 26 CpGs).
