Most of the region coding for the kinase-like domain of aln is replaced by a '3xP3-DsRed' cassette.
DNA encoding aln amino acids 196-402 ( 3L:994851..995531 ) is deleted and replaced by DNA encoding the AttP_LoxP_3xP3-DsRed_LoxP3 cassette from FBrf0224650 Gratz et al. Genetics. 2014 Apr;196(4):961-71.
