MER131 (DF0000727)

Putative SINE of unknown origin, MER131


There are several hundred copies per genome in mammals and chicken. The poly(A) tail is a hallmark of SINE elements, and is thus putatively classified as a SINE element. 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.
