Strains carrying this gene

Strain Genotype Description
KG421 gsa-1(ce81) I. Coordinated hyperactive locomotion. Hypersensitive to mechanical stimuli. Most mature adults have vulval bump. Mature animals are slightly short and egl-d. Terminal phenotype is usually bag of worms. Population tends to severely crash within 2-3 weeks of starvation. Dominant, gain-of-function allele. Heterozygotes are difficult to distinguish from homozygotes. Mutation is R182C. This same mutation causes constitutive Gs activity in vertebrates. Sequence in WT: CCT TCG GTG TCG. Sequence in ce81: CCT TCG GTG TTG.
KG524 gsa-1(ce94) I. Short. Relatively constant motion (coordinated hyperactivity). Adults quickly become Egl-d and most have vulval bump. Hypersensitive to stimuli. Loopy backing, but does not like to back, especially after repeated stimuli. Terminal phenotype is usually bag of worms. Population tends to severely crash after 2-3 weeks of starvation. Dominant, gain-of-function allele. Heterozygotes are also hyperactive and difficult to tell apart from homozygotes. Mutation is G45R. Sequence in WT: GGC GCC G GA GAG AGC. Sequence in ce94: GGC GCC A GA GAG AGC.
NL542 gsa-1(pk75) I; pkEx270. pkEx270 [rol-6(su1006) + gsa-1(+)]. pk75 is an L1 larval lethal. The strain segregates Rollers and L1 lethals.
VC4110 gsa-1(gk5168[loxP + myo-2p::GFP::unc-54 3' UTR + rps-27p::neoR::unc-54 3' UTR + loxP])/+ I. Apparent homozygous lethal or sterile deletion as unbalanced heterozygote. Deletion of 2926 bp with Calarco/Colaiacovo selection cassette conferring myo-2::GFP and G418 resistance inserted at break. Pick viable fertile GFP+ animals to maintain. Left flanking sequence: TGATCCGATTGCGAACGTTCGATCCCCAAC. Right flanking sequence: CAAAGTCGACGTTGTGCGACAGAACAACTA. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.
