Evolutionary history of 7SL RNA-derived SINEs in Supraprimates

Jan Ole Kriegs et al. Trends Genet. 2007 Apr.

Abstract

The evolutionary relationships of 7SL RNA-derived SINEs such as the primate Alu or the rodent B1 elements have hitherto been obscure. We established an unambiguous phylogenetic tree for Supraprimates, and derived intraordinal relationships of the 7SL RNA-derived SINEs. As well as new elements in Tupaia and primates, we also found that the purported ancestral fossil Alu monomer was restricted to Primates, and provide here the first description of a potential chimeric promoter box region in SINEs.
