Strains carrying this gene

Strain Genotype Description
BC2010 let-60(s1124) unc-22(s7) unc-31(e169) IV/nT1 (IV;V). Heterozygotes are WT and segregate WT, Vul and UncLethals. Strong allele of let-60. Unc Twitchers arrest as rod-like early larvae; rare escapers die as Vul adults.
BC2029 let-60(s1155) unc-22(s7) unc-31(e169) IV/nT1 (IV;V). Heterozygotes are WT and segregate WT, Vul and Twitcher UncLethals. s1155 is viable; 14% Vul.
BC966 let-60(s59) unc-22(s7)/unc-5(e152) dpy-4(e1166) IV. Heterozygotes are WT and segregate WT, DpyUnc, and Lethal Twitchers. Lethal mid-larval (leaky). Heterozygotes twitch in nicotine.
DR1172 let-60(s59) unc-22(s7) IV/nT1 [let-?(m435)] (IV;V). Heterozygotes are WT and segregate WT, Lethal Twitchers, and dead eggs. Lethal mid-larval (leaky). Maintain by picking WT. Heterozygotes twitch in 1% nicotine.
MH1131 soc-2(ku167) let-60(n1046) IV. Less than 5% Muv. Previously called sur-8(ku167).
MH231 let-60(n1046) IV; ksr-1(ku68) X. Semi-dominant suppressor of let-60(n1046). Strong reduction of function mutation. At 20C: <1% Muv, 24% Egl, 6% larval lethal, and SM migration defects.
MH351 let-60(sy101sy127)/dpy-20(e1282) IV. Heterozygotes are WT and segregate WT, Dpys and lethals.
MH538 mek-2(ku114) I; let-60(n1046) IV.
MT2124 let-60(n1046) IV. Non-lethal let-60 allele, multivulva phenotype (93% penetrance). Semi-Dominant (17% of hets are Muv). Amber suppressible. Non-null. PKA lin-34. See WBPaper00006902: strain probably carries a side mutation(s) that impairs chemotaxis to the odorant isoamyl alcohol.
MT4244 unc-24(e138) let-60(n1046) IV. Unc. Muv (sd, gf).
MT4574 let-60(n1531)/let-60(n1046) unc-22(e66) IV. Heterozygotes are WT and segregate WT, MuvUnc (n1046 e66) and n1531 homozygotes whose phenotypes range from a few dead larva to sterile adults. The normal larval lethality of n1531/n1531 is suppressed by the maternal contribution of n1046. n1046 is semi-dominant.
MT4698 let-60(n1700) IV. Muv.
MT4700 let-60(n1531) unc-22(e66)/let-60(n1700) dpy-20(e1282) IV; him-5(e1490) V. Heterozygotes are mostly non-Muv (about 20% will be Muv because n1700 is semi-dominant) and non-Unc. Hets segregate Twitchers which die at various larval stages or as Vul adults, because of the maternal effect rescue of n1531 by n1700. The Twitchers will not give viable progeny. Hets also segregate DpyMuvs. The strain segregates males which will mate, though not very well.
MT4725 let-60(n1046) dpy-20(e1282) IV. Dpy (ts). Muv (sd, gf).

MT6400 let-60(n1046) IV; cgr-1(n2528) X. Low penetrance Muv (<5%). Due to variable penetrance larval lethal phenotype at 15C, maintain at 20C.
