Alu sequences.
Alu sequences are frequently encountered during study of human genomic nucleic acid and form a major component of repetitive DNA. This review describes the origin of Alu sequences and their subsequent amplification and evolution into distinct subfamilies. In recent years a number of different functional roles for Alu sequences have been described. The multiple influences of Alu sequences on RNA polymerase II-mediated gene expression and the presence of Alu sequences in RNA polymerase III-generated transcripts are discussed.
