Strain is homozygous viable due to redundancy of act- and act-3 genes. AT 15C, all embyros produced by homozygous mothers hatch; at 26C, 88% of embryos hatch. Deletion which removes 544 nucleotides of act-2 plus the predicted 3' UTR and 705 nucleotides 3' of that. This removes 163/376 amino acids of the act-2 sequence (calculated with ATG methionine included). Sequence of deletion is (text inside of slashes is deleted, with 5' and 3' sequences shown): (exon#2)5'....gtgaaatcgtgcgtgacatc/aaggagaagctttgtt........ ...tggatagacattggtgt/gcgcactccttctggat.....3'(872 nucleotides from stop codon).

Temperature sensitive maternal effect lethal mutation in F11H8.1 (Nedd8 activating enzyme). Permissive temperature is 15C, restrictive temperature is 25C. Embryos layed at restrictive temperature have spindle-orientation defects due to the mis-localization of MEI-1/MEI-2 to the mitotic spindle. Additionally, ectopic cleavage furrows are initiated during cytokinesis, and cell-cycle delays are apparent during interphase.

Heterozygotes are Unc and segregate Uncs, WT which give only dead eggs, and dead eggs. or309 is a deletion allele: removes exon 4 to 3' end and leave about 100 N-terminal amino acids.

mgDf47 completely suppresses daf-c phenotype of daf-2. mgDf47 deletes approximately 8kb of the daf-16 gene beginning after exon 4.

Slow pumping. Egg laying defective. Low frequency of dauer formation. Residual serotonin immunoreactivity, rare and very faint (<1% of NSMs) in most stages, but nearly 100% of CP neurons in adult males show faint to moderate serotonin immunoreactivity. Males mate quite well (E. Hare and C. Loer). Some phenotypic defects originally attributed to mg280 in this strain are likely due to vs166. vs166 is a large deletion (approx. 9.8kb) in the cam-1 gene; flanking sequences are: 5'-gctactggtaaataaggtaa-3' and 5'-atgcttttaaagtttatatt-3' (Edith Myers, personal commnication). See MT15434 for a strain carrying mg280 without the cam-1 mutation.
