Comments

The BS element is a LINE-like transposable element. It has no terminal repeats, an A-rich sequence at the 3' end of the coding strand and two long open reading frames. The first open reading frame contains motifs characteristic of the gag gene of retroviruses and the second contains motifs characteristic of reverse transcriptase.

First described as a sequence inserted within the gypsy element associated with the acHw-1 mutation. It was reported to have inverted terminal repeats of 2.5 kb, but according to the annotation of EMBL AC X77571 this is not so. The sequence of the internal domain is well conserved in the genome (Livingstone and Finnegan). Restriction map in Lindsley, Zimm (1992) p. 1098.
