The canonical 280-bp Alu sequence is composed of two monomers, derived from the 7SL RNA gene, separated by an adenosine rich connector. The consensus AluSc sequence (A) contains an ERE-like sequence (red) identified in the 3′ monomer of the element. A similar element (blue) also occurs in the 5′ monomer of the Alu element. The monomers are separated by an A-rich connector sequence (underlined). The previously indentified Alu-Retinoic Acid Receptor response element (RARE) sequence is also indicated (purple). (B) Diverse ERE-like sequences located in the 3′-monomers of classical Alu element family sequences are indicated. Mismatches from the consensus ERE sequence are indicated by lower case letters.
