  1. ...of the active Alu elements belong to the younger subfamilies. We present a systematic analysis evaluating the observed sequence variation in the different sections of an Alu element on retrotransposition. The length of the longest number of uninterrupted adenines in the A-tail, the degree of A-tail...
  2. ...is necessary for Alu mobilization, although the binding of two heterodimers provides more efficient mobilization. Alu RNPs, once formed, can dock on ribosomes. As L1 mRNA is translated, the poly(A) tail of an SRP9/14-bound Alu competes for nascent L1 ORF2 reverse transcriptase ( Sinnett et al. 1991 ; Boeke...
  3. ...frequency of births/deaths over their entire length, while GC-rich Alu s only in their 3′ poly(A) tails and middle A-stretches, with differences depending on transposable element integration timing. Births/deaths were strongly selected against in coding regions. Births/deaths occurred in genomic regions...
  4. ...in retrotransposition capability has been observed in members of the L1 subfamily ( Lutz et al. 2003 ) and within Alu may be attributable to variation at PolIII promoter efficiency, variation in target-primed reverse transcription, oligo dA tail instability ( Roy-Engel et al. 2002b ), and insertion status polymorphism...
  5. .... 2022). To investigate full-length transcripts, we used LRCAGE reads to call transcripts because LRCAGE reads span from the 5′ end to poly(A) tail. Then, we filtered out transcripts whose 5′ ends were not supported by the merged peaks of LRCAGE and nanoCAGE peaks, resulting in 43,665 full...
  6. .... 2009; Konkel et al. 2010). A full-length Alu element is ∼300 bp in length and terminates in an adenosine-rich tail (A-tail), a typical characteristic of non-LTR retrotransposons (Batzer and Deininger 2002). L1 predates the origin of primates, has been active throughout the radiation of primates...
  7. ...DNA Fragmentase, mix by vortexing, incubate at 37°C for 20 min, stop with 15 µL 0.5M EDTA mixed by pipetting). The resulting fragmented DNA was purified with Zymo Clean and Concentrator 5 µg and eluted with NEB DNA elution buffer. We then end repaired the DNA using NEB end repair kit and added dA tails using NEB...
  8. ...the same patients (Supplemental Table S1). To create a high-confidence insertion set, we included insertion candidates when Tea predicted both target site duplication (TSD) of at least 5 bp and poly(A) tails, the two signatures for target-primed reversed transcription (TPRT)-mediated retrotransposition...
  9. ...indicates that the majority of these insertions (predominately Alu) were assembled near their full length (;300 bp). Manual inspection (Methods) of TIGRA contigs confirmed that many Alu elements were completely assembled not only with polyA tails but also with flanking sequences attached on both ends...
  10. ...of the env gene and the 39-LTR of the endogenous retrovirus HERVK-10 (Ono et al. 1987). A poly(A) tail is positioned downstream of the predicted conserved polyadenylation signal AATAAA (Ostertag et al. 2003). The origin of SVA elements can be traced back to the beginnings of hominid primate evolution, only...
