Mobilization of the progenitor insertion, resulting in deletion of sequences from the P{EP}TrlEP3184 insertion site to the 3' non-coding region of Trl.
Inferred boundaries of a deletion resulting from the imprecise excision of P{EP}TrlEP3184. The deletion extends from the insertion site in the long second intron of the Trl gene to a site 218 bp past the 3' end of the gene.
