The extent of Ds1 transposon to enrich transcriptomes and proteomes by exonization.

ABSTRACT:

Background

Exonization is an event which an intronic transposed element (TE) provides splice sites and leads to alternatively spliced cassette exons. Without disrupting of the inserted gene's function, TEs can expand the proteome diversity by adding the splice variant that encodes a different, yet functional protein. Previously, we found that the main contribution of Ds exonization for gene divergence is not providing genetic messages but incorporating the intron sequences with different reading frame patterns to enrich the plant proteome. Ds1, another member of Ac/Ds transposon system, differs from Ds by providing 3 splice donor sites and 2 acceptor sites for alternative splicing, which may greatly increase the extent for proteome expansion.
