SZ340 smg-4(az152) V. CRISPR/Cas9 engineered smg-4 null allele. smg-4(az152) allele is confirmed NMD-defective by both the presence of the protruding vulva phenotype and the accumulation of NMD-targeted isoforms. smg-4(az152) is easy to track in crosses by PCR and digestion with BstBI (see S1 text of Suzuki, et al. for sequence of allele) and essentially mimics ma116 in having a G->A mutation at the last base of intron 1. az152 also removes two bases of exon 2 and inserts 50nt in exon 2. Reference: Suzuki JMNGL, et al. PLoS Genet. 2022 Feb 10;18(2):e1010028. doi: 10.1371/journal.pgen.1010028. PMID: 35143478.
SZ345 unc-73(e936az30) dxbp-1(az121) I; smg-4(az152) V. dxbp-1(az121) is a K23N mutation that promotes usage of introns starting in UU when the sequence GUU is present at the 5' end of the intron. az121 was initially identified as able to suppress uncoordination of unc-73(e936) by promoting a cryptic splice site that defines an intron beginning UU. smg-4 mutant background allows for high throughput sequencing to identify frame shifted transcripts since it can move the 5'ss over by 1nt. e936az30 has no phenotype on its own, but it offers two adjacent cryptic 5'ss separated by 1nt. Reference: Suzuki JMNGL, et al. PLoS Genet. 2022 Feb 10;18(2):e1010028. doi: 10.1371/journal.pgen.1010028. PMID: 35143478.

SZ355 unc-73(az63) dxbp-1(az52) I; smg-4(az152) V. az52 is a CRISPR-engineered M107I missense allele of dxbp-1. az52 has no phenotype on its own, but suppresses unc-73(e936) and unc-73(az63) by promoting use of a cryptic splice site for an intron beginning with UU. smg-4(az152) provides an NMD deficient background allowing identification of out-of-frame mis-splicing in an RNA-seq experiment. Reference: Suzuki JMNGL, et al. PLoS Genet. 2022 Feb 10;18(2):e1010028. doi: 10.1371/journal.pgen.1010028. PMID: 35143478.

SZ197 unc-73(e936) I; prp-8(az50) III. prp-8(az50) is a T524S missense allele that affects cryptic splicing (5'ss choice) of unc-73(e936) to allow more UNC-73 protein to be produced. PRP-8 is the largest protein in the spliceosome (essential) with a role in all stages of splicing. Reference: Mayerle M, et al. Proc Natl Acad Sci U S A. 2019 Feb 5;116(6):2193-2199. doi: 10.1073/pnas.1819020116. PMID: 30674666.

Reference: Cartwright-Acar CH, et al. Nucleic Acids Res. 2022 Nov 11;50(20):11834-11857. doi: 10.1093/nar/gkac991. PMID: 36321655.

ZT49 ego-1(fj114[PA::ego-1]) I. Four amino-acid residues (G24–V27) near the N-terminus of EGO-1 were replaced with a PA-tag sequence (GVAMPGAEDDVV derived from human podoplanin) in the endogenous ego-1 gene. The PA-tag insertion can be checked by PCR with the following primers: TTCAAAATGCCGCTGCCTTC and GTCCTCTTCGCATCTTTATCAG, followed by digestion with Sau96I. The wild-type ego-1 gene contains a Sau96I site within its PCR region, while the PA-tagged ego-1 does not. This strain was used for immunofluorescence analysis of EGO-1. Reference: Tabara H, et al. (2023) A small RNA system ensures accurate homologous pairing and unpaired silencing of meiotic chromosomes. EMBO J, e105002.
ZT73 coh-4(tm1857) coh-3(gk112)/tmC16 [unc-60(tmIs1210)] coh-3(gk112) V. Pick wild-type Venus+ animals to maintain. coh-4(tm1857) coh-3(gk112) homozygotes exhibit defects in synaptonemal complex formation on meiotic chromosomes. Many of the progeny from coh-4 coh-3 homozygotes exhibit embryonic lethality, likely due to aneuploidy, but only a few progeny hatch and exhibit the Him phenotype. The coh-3 and coh-4 genes encode nearly identical meiosis-specific kleisins. The deletion mutations can be checked by PCR with the following primers: coh-4(tm1857): TACGCGGCACACATGGGTCT and CAATTCCCCCTAGACATACGATTC; coh-3(gk112): CTCGCAGCGATCGAGCAAGC and AACTGAACATGAGAGCCACGAAG. tmC16 homozygotes are Unc Venus(+). [NOTE: ZT73 with the inversion-based balancer is more amenable to producing coh-4 coh-3 homozygous mutant males than TY5120 with a translocation-based balancer.] Reference: Tabara H, et al.
