Examples of direct repeats flanking diverse processed pseudogenes from GenBank 97.0. GenBank accession numbers are listed before each sequence. The flanking repeats are indicated in uppercase letters and the adjacent sequences in lowercase. The omitted portion of each pseudogene is marked by ∼. The pseudogenes listed are as follows: (I) human ferritin H, α-enolase, cytoplasmic 7SL RNA, thiopurine methyltransferase, β-tubulin, γ-actin-like, and chromosomal protein HMG-17; (II) rodent α-tubulin, δ-aminolevulinate dehydratase, cytoplasmic γ-actin, metallothionein 1, cellular tumor antigen p53, small nuclear RNA U3 (rat), small nuclear 4.5S RNA(I), small nuclear RNA U3 (mouse), ribosomal protein L35a-related, thymidine kinase, VH 7183 family for immunoglobulin heavy chain, 7SK RNA, cytochrome oxidase subunit VIa, and acyl-CoA-binding/diazepam binding inhibitor; (III) other mammals, rabbit short interspersed C repeat (SINE) and B2-like repeat from mink; and (IV) frog (Rana catesbeiana) apoferritin pseudogene.
