Organization of subtelomeric repeats in Plasmodium berghei.

ABSTRACT: Several (but not all) Plasmodium berghei chromosomes bear in the subtelomeric position a cluster of 2.3-kilobase (kb) tandem repeats. The 2.3-kb unit contains 160 base pairs of telomeric sequence. The resulting subtelomeric structure is one in which stretches of telomeric sequences are periodically spaced by a 2.1-kb reiterated sequence. This periodic organization of internal telomeric sequences might be related to chromosome-size polymorphisms involving the loss or addition of subtelomeric 2.3-kb units.

Organization and evolution of subtelomeric satellite repeats in the potato genome.

Project description:Subtelomeric domains immediately adjacent to telomeres represent one of the most dynamic and rapidly evolving regions in eukaryotic genomes. A common feature associated with subtelomeric regions in different eukaryotes is the presence of long arrays of tandemly repeated satellite sequences. However, studies on molecular organization and evolution of subtelomeric repeats are rare. We isolated two subtelomeric repeats, CL14 and CL34, from potato (Solanum tuberosum). The CL14 and CL34 repeats are organized as independent long arrays, up to 1-3 Mb, of 182 bp and 339 bp monomers, respectively. The CL14 and CL34 repeat arrays are directly connected with the telomeric repeats at some chromosomal ends. The CL14 repeat was detected at the subtelomeric regions among highly diverged Solanum species, including tomato (Solanum lycopersicum). In contrast, CL34 was only found in potato and its closely related species. Interestingly, the CL34 repeat array was always proximal to the telomeres when both CL14 and CL34 were found at the same chromosomal end. In addition, the CL34 repeat family showed more sequence variability among monomers compared with the CL14 repeat family. We conclude that the CL34 repeat family emerged recently from the subtelomeric regions of potato chromosomes and is rapidly evolving. These results provide further evidence that subtelomeric domains are among the most dynamic regions in eukaryotic genomes.

Structural ordering of the Plasmodium berghei circumsporozoite protein repeats by inhibitory antibody 3D11.

Project description:Plasmodium sporozoites express circumsporozoite protein (CSP) on their surface, an essential protein that contains central repeating motifs. Antibodies targeting this region can neutralize infection, and the partial efficacy of RTS,S/AS01 - the leading malaria vaccine against P. falciparum (Pf) - has been associated with the humoral response against the repeats. Although structural details of antibody recognition of PfCSP have recently emerged, the molecular basis of antibody-mediated inhibition of other Plasmodium species via CSP binding remains unclear. Here, we analyze the structure and molecular interactions of potent monoclonal antibody (mAb) 3D11 binding to P. berghei CSP (PbCSP) using molecular dynamics simulations, X-ray crystallography, and cryoEM. We reveal that mAb 3D11 can accommodate all subtle variances of the PbCSP repeating motifs, and, upon binding, induces structural ordering of PbCSP through homotypic interactions. Together, our findings uncover common mechanisms of antibody evolution in mammals against the CSP repeats of Plasmodium sporozoites.

Plasmodium berghei Gametocytogenesis

Project description:Transcriptional profiling of gametocyte non-producer lines in Plasmodium berghei Transcriptome of gametocyte non producer lines (natural and genetic KO) and parental (820) lines. The aim of the study was to identify key genes involved in the decision to commit to gametocytogenesis in Plasmodium berghei. These microarrays compare naturally selected lines that do not produce gametocytes, and the parental line and additionally a genetic knock out of AP2-G PBANKA_143750.

Human subtelomeric duplicon structure and organization.

Project description:BackgroundHuman subtelomeric segmental duplications ('subtelomeric repeats') comprise about 25% of the most distal 500 kb and 80% of the most distal 100 kb in human DNA. A systematic analysis of the duplication substructure of human subtelomeric regions was done in order to develop a detailed understanding of subtelomeric sequence organization and a nucleotide sequence-level characterization of subtelomeric duplicon families.ResultsThe extent of nucleotide sequence divergence within subtelomeric duplicon families varies considerably, as does the organization of duplicon blocks at subtelomere alleles. Subtelomeric internal (TTAGGG)n-like tracts occur at duplicon boundaries, suggesting their involvement in the generation of the complex sequence organization. Most duplicons have copies at both subtelomere and non-subtelomere locations, but a class of duplicon blocks is identified that are subtelomere-specific. In addition, a group of six subterminal duplicon families are identified that, together with six single-copy telomere-adjacent segments, include all of the (TTAGGG)n-adjacent sequence identified so far in the human genome.ConclusionIdentification of a class of duplicon blocks that is subtelomere-specific will facilitate high-resolution analysis of subtelomere repeat copy number variation as well as studies involving somatic subtelomere rearrangements. The significant levels of nucleotide sequence divergence within many duplicon families as well as the differential organization of duplicon blocks on subtelomere alleles may provide opportunities for allele-specific subtelomere marker development; this is especially true for subterminal regions, where divergence and organizational differences are the greatest. These subterminal sequence families comprise the immediate cis-elements for (TTAGGG)n tracts, and are prime candidates for subtelomeric sequences regulating telomere-specific (TTAGGG)n tract length in humans.

Plasmodium berghei PbeIK2KO sporozoites

Project description:Malaria sporozoites, the form transmitted by mosquitoes, are quiescent while in the insect salivary glands. It is only after the sporozoites are deposited in the host’s skin, migrate to the liver and infect hepatocytes that the parasites continue the life cycle. We show that the sporozoite latency is an active process that requires phosphorylation of the eukaryotic initiation factor-2α (eIF2α) by a sporozoite-specific kinase. Inactivation of the kinase gene leads to an overall enhancement of protein synthesis including of silenced liver stage proteins, and inhibits transmission of malaria. Specific inhibition of the eIF2α phosphatase by salubrinal has the opposite effect. Thus, to prevent premature transformation into liver stages, Plasmodium sporozoites exploit the same mechanism that regulates stress responses in mammalian cells.
