Abstract

BACKGROUND: Short interspersed elements (SINEs) are ubiquitous components of eukaryotic genomes. SINEs are composite transposable elements that are mobilized by non-long terminal repeat (non-LTR) retrotransposons, also called long interspersed elements (LINEs). The 3' part of SINEs usually originated from that of counterpart non-LTR retrotransposons. The 5' part of SINEs mostly originated from small RNA genes. SINE1 is a group of SINEs whose 5' part originated from 7SL RNA, and is represented by primate

RESULTS: Here a new lineage of SINE1 is characterized from the seashore hagfish

CONCLUSIONS: The hagfish SINE1 is the first evident SINE1 family found outside of Euarchontoglires. Independent evolution of SINE1 with similar RNA secondary structure originated in 7SL RNA indicates the functional importance of 7SL RNA-derived sequence in the proliferation of SINEs.
