Construct: 4.6kb SalI-EcoRI genomic fragment including the Aats-asn, l(2)37Ce and l(2)37Cg transcription units. Position of restriction fragment on reference sequence inferred by FlyBase curator. The position of the EcoRI site is approximate because their is no EcoRI site at this location in the reference genome.
Able to rescue the l(2)37Ca- phenotype.
