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