Strains carrying this gene

Strain Genotype Description
BC1925 dpy-18(e364)/eT1 III; sos-1(s1031) unc-46(e177)/eT1 V. WT strain that segregates WT, Unc-36 (eT1 homozygotes), and dead eggs. s1031 is an egg lethal. Maintain by picking WT. Previously called let-341(s1031).
HP17 sos-1(pd10) V. sos-1 gain-of-function allele originally isolated as a suppressor of sem-5(n1619) lethality. pd10 causes a E99K substitution within the N-terminal histone fold domain of SOS-1. Single mutants appear wild-type.
HP23 sos-1(pd9) V. sos-1(pd9) is a gain-of-function allele causing a C662Y substitution within the Ras exchange motif of SOS-1. Originally isolated as a suppressor of sem-5(n1619) lethality. Single mutants appear wild-type. Reference: Wooller A & Hopper N. (2014) European Worm Meeting. (Anyone using this allele may cite Neil Hopper as a personal communication based on this meeting abstract.)
UP604 sos-1(cs41) V. Temperature sensitive missense allele. Larval lethal and Vul at 25C. About WT at 20C. Previously called let-341.
VC2670 sos-1(ok3565) V/nT1 [qIs51] (IV;V). T28F12.3. Apparent homozygous lethal deletion chromosome balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok3565 homozygotes (arrest stage/phenotype undetermined). Any viable non-GFP progeny are not homozygous mutants but rare recombinant heterozygotes. Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: ATTGGTTGCAGTCAGGGAAG. External right primer: AAAAGCGTGCTCGACAGAAT. Internal left primer: TCGCGATTTGAAAAGTTGTG. Internal right primer: GACAATCACGAAAAGGAAGAGG. Internal WT amplicon: 1126 bp. Deletion size: 884 bp. Deletion left flank: TCTCATCATGATGTCTCGGTATTTTTTTGT. Deletion right flank: CGTATAAGAATGATATGTCAGTCGTTCAAT. Insertion Sequence: ACAAAACAAAATATGCTTGACTTTTT.
