Imprecise excision of the progenitor insertion, resulting in a 1804bp deletion extending from nucleotide 19255898 to nucleotide 19257703 (coordinates according to GenBank accession AE014296). The deletion removes the entire Max open reading frame. The deletion also disrupts the neighbouring CG9666 gene.
An 1804 bp deletion resulting from the imprecise excision of P{EPgy2}Mettl5EY02775 extending from nt 19255898 to nt 19257703 of GB:AE014296.4. Deletion affects both Max and Mettl5.
Df(3L)Max1 flies rescued by P{Max+t2.788} (which does not contain any part of the CG9666 open reading frame) are fully viable and fertile, have a wild-type weight and show no phenotypic defects.
