Short interspersed elements (SINEs) are ubiquitous in mammalian genomes. Remarkable variety of these repeats among placental orders indicates that most of them amplified in each lineage independently, following mammalian radiation. Here, we present an ancient family of repeats, whose sequence divergence and common occurrence among placental mammals, marsupials and monotremes indicate their amplification during the Mesozoic era. They are called MIRs for abundant Mammalian-wide Interspersed… Expand
Evolutionary inventions and continuity of CORE-SINEs in mammals.
TLDR
A model in which new CORE-families, with distinct 3'-segments, are created at the RNA level due to template switching between LINE and Core-RNA during reverse transcription is proposed. Expand
MIR: Family of repeats common to vertebrate genomes
TLDR
MIRs were detected in genomes of various fishes, including Latimeria, which suggests that the origin of MIRs dates back more than 400 million years. Expand
CORE-SINEs: eukaryotic short interspersed retroposing elements with common sequence motifs.

TLDR
It is proposed that the core identifies an ancient tRNA-like SINE element, which survived in different lineages such as mammals, reptiles, birds, and fish, as well as mollusks, presumably for >550 million years. Expand
Sauria SINEs: Novel Short Interspersed Retroposable Elements That Are Widespread in Reptile Genomes
TLDR
It is proposed that all Sauria SINEs utilize the enzymatic machinery of Bov-B LINEs for their own retrotransposition, suggesting that these LINEs have been an active partner of SauriaSINEs since this SINE family was generated more than 200 million years ago. Expand
Identification of an ancient endogenous retrovirus, predating the divergence of the placental mammals
TLDR
This study describes, for the first time, a retroviral orthologue predating the divergence of placental mammals, giving it a minimum age of 104–110 Myr, and other orthologous selfish genetic elements (SGEs), inserted into the ERV sequence, provide evidence for the oldest individual mammalian-wide interspersed repeat and medium-reiteration frequency interSpersed repeat mammalian repeats, with the same minimum age.

Artiodactyl interspersed DNA repeats in cetacean genomes
TLDR
It is shown that the ancient short interspersed elements (SINEs) ARE1 and ARE2 are abundantly present in the genomes of artiodactyls and cetaceans but not in other mammalian genomes, which supports the classification of the cetACEans with the artiodACTyls by a shared character that is unlikely to be the result of convergence. Expand
Evolutionary implications of multiple SINE insertions in an intronic region from diverse mammals
TLDR
An analysis of the nuclear β-fibrinogen intron 7 locus from 30 taxa representing 12 placental orders of mammals reveals the enriched occurrences of short interspersed element (SINE) insertion events, indicating that SINEs have a greater insertional flexibility and regional specificity than had previously been recognized.

SINE insertions: powerful tools for molecular systematics.

TLDR
This review covers the basic aspects of SINE evolution that are especially relevant to their use as systematic characters and describes the practical methods of characterizing SINEs for cladogram construction. Expand
Short Interspersed Elements (SINEs)
TLDR
Short interspersed elements are highly repetitive sequences that retrotranspose into eukaryotic DNA through intermediates transcribed by RNA polymerase III (pol III) and are widely considered to be examples of ‘selfish’ or ‘parasitic’ DNA. Expand
Retroposons of salmonoid fishes (Actinopterygii: Salmonoidei) and their evolution.
TLDR
The aim of the present review is to structure all knowledge accumulated about salmonoid retroposons by now, as well as to complement it with the new data pertaining to the distribution of some SINE families. Expand
