A 6.1kb SalI genomic fragment containing the e(r) coding sequence, into which amino acid substitutions T18A and T63A have been introduced.
e(r)T18A.T63A rescues e(r)p2
e(r)T18A.T63A rescues e(r)p1
e(r)T18A.T63A suppresses the ability of e(r)p1 to enhance the mutant wing phenotype of rhd1-12.
e(r)T18A.T63A suppresses the synthetic lethality caused by e(r)p2 in combination with Nnd-p.
