Figure 4From: TAPDANCE: An automated tool to identify and annotate transposon insertion CISs and associations between CISs from next generation sequence dataSB transposon mapping and Orientation. A) The SB transposon is asymmetric and can map in either + or – orientation within specific TA sites. B) Genomic region after insertion of SB transposon in either + orientation (red) capable of driving transcription of genes encoded on the positive strand or in – orientation (blue) capable of driving genes encoded on the – strand. In either direction a splice site acceptor is available, leading to transcript disruption. PCR products derived from SB junction fragments are capable of determining which orientation the transposon has integrated. The sets of primers i-iv indicate how the PCR products are obtained. Each of the transposon side primers contains a library specific barcode to allow multiplexing during the sequencing process.Back to article page
