Yunjia Tang et al.
Background: Twin-ribozyme introns represent a complex class of mobile group I introns that harbour a lariat capping (LC) ribozyme and a homing endonuclease gene embedded in a conventional self-splicing group I ribozyme (G...
Analysis of CACTA transposases reveals intron loss as major factor influencing their exon/intron structure in monocotyledonous and eudicotyledonous hosts [0.03%]
CACTA转座酶的分析揭示了外显子/内含子结构在单子叶和双子叶植物宿主中的变化主要是由于内含子丢失所致

Background: CACTA elements are DNA transposons and are found in numerous organisms. Despite their low activity, several thousand copies can be identified in many genomes. CACTA elements transpose using a 'cut-and-paste' m...

Processed pseudogenes are copies of messenger RNAs that have been reverse transcribed into DNA and inserted into the genome using the enzymatic activities of active L1 elements. Processed pseudogenes generally lack introns, end in a 3' poly...
CRISPR-Cas immunity and mobile DNA: a new superfamily of DNA transposons encoding a Cas1 endonuclease [0.03%]

Mobile genetic elements such as DNA transposons are a feature of most genomes. The existence of novel DNA transposons can be inferred when whole genome sequencing reveals the presence of hallmarks of mobile elements such as terminal inverte...

Transposable elements (TEs) are major structural components of eukaryotic genomes; however, mobilization of TEs generally has negative effects on the host genome. To counteract this threat, host cells have evolved genetic and epigenetic mec...
The Drosophila mojavensis Bari3 transposon: distribution and functional characterization [0.03%]
嗜氢果蝇Bari3转座子的分布及功能表征
Antonio Palazzo,Roberta Moschetti,Ruggiero Caizzi et al.
Antonio Palazzo et al.
Background: Bari-like transposons belong to the Tc1-mariner superfamily, and they have been identified in several genomes of the Drosophila genus. This transposon's family has been used as paradigm to investigate the comp...
Modular organization and reticulate evolution of the ORF1 of Jockey superfamily transposable elements [0.03%]

Background: Long interspersed nuclear elements (LINES) are the most common transposable element (TE) in almost all metazoan genomes examined. In most LINE superfamilies there are two open reading frames (ORFs), and both a...
Mammalian-wide interspersed repeat (MIR)-derived enhancers and the regulation of human gene expression [0.03%]
哺乳动物广泛分散重复序列(MIR)衍生的增强子与人类基因表达调控
Daudi Jjingo,Andrew B Conley,Jianrong Wang et al.
Daudi Jjingo et al.
Background: Mammalian-wide interspersed repeats (MIRs) are the most ancient family of transposable elements (TEs) in the human genome. The deep conservation of MIRs initially suggested the possibility that they had been e...
DINE-1, the highest copy number repeats in Drosophila melanogaster are non-autonomous endonuclease-encoding rolling-circle transposable elements (Helentrons) [0.03%]
