“…The human genome contains traces of 10 clades (L1, CR1, L2, Crack, RTE, RTEX, R4, Vingi, Tx1 and Penelope) of non-long terminal repeat (non-LTR) retrotransposons (long interspersed elements, LINEs), 3 types (SINE1/7SL, SINE2/tRNA, and SINE3/5S) of short interspersed elements (SINEs), 1 composite retrotransposon (SVA) family, 5 classes (ERV1, ERV2, ERV3, Gypsy and DIRS) of LTR retrotransposons, and 12 superfamilies (Crypton, Ginger1, Harbinger, hAT, Helitron, Kolobok, Mariner, Merlin, MuDR, P, piggyBac and Transib) of DNA transposons. …”

“…We find that TEs encompass a quarter of the human regulatory epigenome, and 47% of elements can be in an active regulatory state. We demonstrate that SINEs are enriched relative to other classes for active and transcribed marks, that TEs encompass a higher proportion of enhancer states in the hematopoietic lineage, and that DNA methylation of Alu elements decreases with age, corresponding with a loss of CpG islands. …”

“…RNA-binding intrinsically disordered domains (IDRs) of CHD4 are required to prevent this aberrant CTCF binding, and CHD4 is critical for the repression of B2 SINE transcripts. These results collectively reveal that a CHD4-mediated mechanism ensures appropriate CTCF binding and associated TAD organization in mESCs.…”

“…Such elements are human endogenous retroviruses (HERVs) and non-long terminal repeat (non-LTR) retrotransposons, including long and short interspersed nuclear elements (LINEs and SINEs). In line with their parasitic origin and selfish behaviour, retrotransposon-imposed gene regulation is a major source of genetic variation and instability in the human genome, and may represent the missing link between genetic susceptibility and environmental factors long thought to contribute to T1D onset. …”

“…These mRNA retroposition events fall into three categories: I) 34 retrocopies and antisense retrocopies that added potential protein coding space and UTRs to existing genes; II) 682 complete retrocopy duplications inserted into new loci; and III) an unexpected set of 13 retrocopies that contributed out-of-frame, or antisense sequences in combination with other types of transposed elements (SINEs, LINEs, LTRs), even unannotated sequence to form potentially novel genes with no homologs outside primates. …”
