A 6.1kb SalI genomic fragment containing the e(r) coding sequence, into which amino acid substitutions S24E and T63E have been introduced.
e(r)S24E.T63E rescues e(r)p2
e(r)S24E.T63E rescues e(r)p1
e(r)S24E.T63E suppresses the ability of e(r)p1 to enhance the mutant wing phenotype of rhd1-12.
e(r)S24E.T63E suppresses the synthetic lethality caused by e(r)p2 in combination with Nnd-p.
