MER45R (DF0000788)

hAT-Tip100 DNA transposon, MER45R subfamily (non-autonomous)


MER45R is a hAT-like DNA transposon encoding a protein related to that of Zaphod and "activator-like" transposases in Arabidopsis (e.g. GID 4538984). It is an internal deletion product of an autonomous element (N-terminal half of gene is missing). It has 15 bp TIRs, 8 bp TSDs. Initially reported in the opposite orientation. 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.
