MER125 (DF0000722)

Unclassified, putative DNA transposon, MER125 subfamily

Description

MER125 is found in mammals and chicken at ~200 copies. A smaller number of copies are identified in Xenopus. MER125 has 20 bp TIRs, and a possible preference for AATT TSDs (not same as TTAA of piggyBac group). Consensus sequences derived from human and chicken genomes are ~95% identical, suggesting conservation. Note that MER stands for MEdium Reiteration frequency interspersed repeat. As such, MERs as a group are a grab bag of DNA transposons and retrotransposons.
