Duplicated pseudogenes

WebJul 8, 2010 · Duplicated pseudogenes are formed when the new sequence undergoes mutations that result in the loss of original function. In contrast, processed pseudogenes arise from retrotransposition events [typically indicated by the lack of introns and presence of a 3′-poly(A) tail] (7, 8). They usually lack promoter sequences, and hence are considered ... WebDuplicated pseudogenes arise from genomic DNA duplication or unequal crossing over. They retain the original exon–intron organization of the functional gene (hence nonprocessed), but their protein-coding potential is lost because of the loss of transcription regulatory elements, such as promoters or enhancers, or mutations disrupting the ORF ...

Webing processed and duplicated pseudogenes [19,3,4,20,2]. First we identify pseudogene candidates by aligning the genome in all six frames of the translated amino acid sequences to the known proteins in the organism [21]. Then we distinguish pseudogenes from their parent genes by identifying disablements such as insertions, deletions, Webof the VH1 gene by the many duplicated variable region pseudogenes that occur on its 5 0 side [27].
