Comments

The spatial and temporal expression patterns of fifteen families of retrotransposons are analysed during embryogenesis and are found to be conserved. Results suggest that all families carry cis-acting elements that control their spatial and temporal expression patterns.

First described by Karlik and Fyrberg (1985) as an insertion in the gene for an indirect-flight-muscle-specific tropomyosin isoform associated with the mutation Tm1. The map and sequence of an LTR were reported by Karlik and Fyrberg. There are no sites for the enzyme BamHI. This element and a copy associated with the mutation Nfa-3 are both flanked by the sequence TATATA; this is probably the target site duplication, although it could be part of the inverted repeats at the end of the LTR.
