Insertion of a P{GTD-b} element within an intron.
viable
The gene trap line "GTDexp1-#31/1-GTDexp1-#2/2" contains two P{GTD-b} insertions - P{GTD-b}bratGTD1-31.1 and P{GTD-b}bratGTD1-2.2, both of which are in an intron of brat.
The P{GTD-b}bratGTD1-2.2 insertion maps in an intron of brat, and is also downstream of BEST:SD07237 (which is itself contained within the brat intron). The gene "trapped" by the P{GTD-b}bratGTD1-2.2 insertion (to which the Scer\GAL4GTD-b.T:Mmus\Trp53 coding sequence fuses) is BEST:SD07237.
