This strain forms 20% dauers at 15C. At 25C there occurs about 25% embryonic arrest and about 75% L1 arrest. The e979 mutation results in an amino acid substitution, C146Y, in the ligand-binding domain of the DAF-2 receptor. [CGC received new stock of DR1942 September 2002. Previous stock was probably m41 and not e979.] [June 2004: Patrice Albert has confirmed the mutation in this stock: Repeat of sequencing for CGC collection strain DR1942 [daf-2(e979)] is complete. The strain does carry a C146Y mutation (coding strand TGC to TAC) [Mutation position is at 143, not 146, based on the amino acid sequence shown in Wormbase for daf-2. It's the C in partial sequence EKRCGPI of Exon 5.].]

C17C3.8 Homozygous. Outer Left Sequence: ccagttccgcctgtaacatt. Outer Right Sequence: ttgccacgactggatattga. Inner Left Sequence: actcacctctgcaactgcct. Inner Right Sequence: agtgtcacacgctgagatgg. Inner Primer PCR Length: 2179. Deletion Size: 983 bp. Additional information from Casonya Johnson 3/2005: the deletion is 983 bases, from base 2254 to 3237 on the cosmid C17C3. The gene C17C3.8 is on the opposite strand, and its coding region is from bases 3237 to 3616. The deletion occurs within the second exon of the gene, so that the first 105 amino acids of the protein are still made. This region contains one of the two HLH domains produced by this protein but eliminates the second one. The first stop codon would allow another 19 amino acids to be added to the peptide. I have pasted the sequence below (the red, underlined sequences are the new nucleotides).
