Alu element-mediated gene silencing.
The Alu elements are conserved approximately 300-nucleotide-long repeat sequences that belong to the SINE family of retrotransposons found abundantly in primate genomes. Pairs of inverted Alu repeats in RNA can form duplex structures that lead to hyperediting by the ADAR enzymes, and at least 333 human genes contain such repeats in their 3'-UTRs. Here, we show that a pair of inverted Alus place...
متن کاملAn Alu element retroposition in two families with Huntington disease defines a new active Alu subfamily.
Alu repetitive elements represent the most common short interspersed elements (SINEs) found in primates, with an estimated 500,000 members in the haploid human genome. Considerable evidence has accumulated that these elements have dispersed in the genome by active transcription followed by retroposition, and that this process is ongoing. Sequence variation between the individual elements has le...
متن کاملRecent insertion of an Alu element within a polymorphic human-specific Alu insertion.
Alu elements are a family of short interspersed repeats that have mobilized throughout primate genomes by retrotransposition over the past 65 Myr of primate evolution (for a review, see Deininger and Batzer 1993). In the human genome, Alu elements exist in copy numbers of approximately 500,000 per haploid genome, representing approximately 5% of the genome, and they may be classified into group...
متن کاملActive Alu element "A-tails": size does matter.
Long and short interspersed elements (LINEs and SINEs) are retroelements that make up almost half of the human genome. L1 and Alu represent the most prolific human LINE and SINE families, respectively. Only a few Alu elements are able to retropose, and the factors determining their retroposition capacity are poorly understood. The data presented in this paper indicate that the length of Alu "A-...
متن کاملHuman DNA quantitation using Alu element-based polymerase chain reaction.
Human forensic casework requires sensitive quantitation of human nuclear DNA from complex sources. Widely used commercially available systems detect both nonhuman and human primate DNA, often require special equipment, and have a detection limit of approximately 0.1ng. Multicopy Alu elements include recently integrated subfamilies that are present in the human genome but are largely absent from...
