[Gu T] sur-5 for suppressors of ras. Mutations in sur-5 suppress the vulvaless phenotype caused by let-60(sy94) dominant negative mutation. sur-5 mutations have no phenotype on their own.
sur-5 is located on a 8kb BamHI fragment that overlaps both K03A1 and R12E12. R12E12 also rescues ku74. The allele ku74 is a inframe deletion that deletes 295 n.t. of the sur-5 genomic sequence.
