| SZ155 | unc-73(e936) I; prp-8(az29) III. | C. elegans | prp-8(az29) is a G654E missense mutation. az29 is a CRISPR-induced mutation mimicking a known suppressor of unc-73(e936). It changes cryptic splicing of e936 to allow for an increase in full-length unc-73 expression. 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. |
| SZ197 | unc-73(e936) I; prp-8(az50) III. | C. elegans | 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. |
| SZ211 | snrp-27(az56) I. | C. elegans | snrp-27(az56) is a M141T missense allele with semi-dominant suppression of e936. No phenotype on its own. az56 is a CRISPR-induced mutation mimicking a known suppressor of unc-73(e936). This allele activates many dozens of alternative 5' splice sites in an RNA-seq experiment. snrp-27 is a component of the tri-snRNP and pre-B spliceosomal complexes. Reference: Zahler AM, et al. RNA. 2018 Oct;24(10):1314-1325. doi: 10.1261/rna.066878.118. PMID: 30006499. |
| SZ299 | unc-73(e936) I; prp-8(az117) III. | C. elegans | prp-8(az117) is a CRISPR-engineered R540K missense allele that suppress unc-73(e936) uncoordination through activation of an in-frame cryptic 5'ss. Reference: Cartwright-Acar CH, et al. Nucleic Acids Res. 2022 Nov 11;50(20):11834-11857. doi: 10.1093/nar/gkac991. PMID: 36321655. |
| SZ304 | unc-73(e936) I; prp-8(az119) III. | C. elegans | prp-8(az119) is a D1549N missense allele. az119 is a CRISPR-induced mutation mimicking a known suppressor of unc-73(e936). az119 suppresses unc-73(e936) uncoordination through activation of cryptic splicing that promotes full length UNC-73 production. Reference: Cartwright-Acar CH, et al. Nucleic Acids Res. 2022 Nov 11;50(20):11834-11857. doi: 10.1093/nar/gkac991. PMID: 36321655. |
| SZ305 | unc-73(e936) I; snrp-200(az123) II. | C. elegans | az123 is an N18K missense allele altering 5' cryptic splicing usage. az123 is a CRISPR-induced mutation mimicking a known suppressor of unc-73(e936). Reference: Cartwright-Acar CH, et al. Nucleic Acids Res. 2022 Nov 11;50(20):11834-11857. doi: 10.1093/nar/gkac991. PMID: 36321655. |
| SZ340 | smg-4(az152) V. | C. elegans | 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. | C. elegans | 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. | C. elegans | 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. |
| SZ370 | snu-66(az160) V. | C. elegans | SNU-66 H765G substitution. No obvious morphological or growth phenotypes were observed. az160 mutation disrupts SNU-66(H765)/SNRP-27(M141) interaction, affecting alternative 5' splice site usage. Worm SNU-66(H765) and SNRP-27(M141) are homologous to human preB spliceosome components snu66(H734) and snrnp27(M141), respectively. Reference: Sarka K, et al. 2024. In submission. |
| SZ454 | mog-5(az192) II. | C. elegans | Directed mutagenesis of mog-5 removed 17 amino acids and inserted 9 different amino acids at the site of structural interface with SACY-1, promoting upstream alternative 3'ss usage in somatic cells in a pattern similar to sacy-1 mutants and similar to a switch that occurs in the germline. Changes alternative 3' splice site usage to upstream 3' splice site in somatic cells for 76 different alternative splicing events. No obvious morphological phenotypes. Reference: Osterhoudt K, et al. RNA. 2024 Jan 24:rna.079888.123. doi: 10.1261/rna.079888.123. PMID: 38282418. |
