Comments

Identified with: RE43210 (BDGP-DGC) <up>FlyBase curator comment: EST subsequently found to be chimeric</up>.

EST RE43210 is chimeric; the 5' portion corresponds to part of roo, the 3' portion corresponds to part of HMS-Beagle.

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.

One substock of inbred lines shows considerable heterogeneity of insertion sites of copia (frequency of insertions is 12% per haploid genome per generation) whereas mdg1, 412, mdg3, gypsy, 297 and HMS-Beagle were stable in all stocks examined.

The HMS-Beagle element has 266bp direct repeats at its termini and is flanked by a duplication of 4bp. It is present approximately 50 times in the haploid genome.

First described as an insertion within the promoter region of the cuticle protein gene, Lcp3n1. The sequence shown in Finnegan (1992) is the reverse complement of that published by Snyder, Kimbrell, Hunkapiller, Hill, Fristrom and Davidson (1982). There are no sites for the enzymes AvaI, BamHI, HindIII, or KpnI.
