43kb genomic fragment (derived from BAC clone RP98-7M13) which encompasses Dif. A 5' splice donor site of Dif has been mutated, resulting in intron retention, such that only the B isoform can be produced.
43kb genomic fragment (derived from BAC clone RP98-7M13) which encompasses both dl and Dif. A 5' splice donor site of Dif has been mutated, resulting in intron retention, such that only the B isoform can be produced.
