Temperature sensitive sterile. Partially sterile at 20 C; completely sterile at 25 C. Maintain at <20 C. Do not distribute this strain; other labs should request it directly from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

Males are rayless. hlh-2(bx108) strongly and semi-dominantly enhances the ray-loss phenotype of lin-32(e1926).

Paralyzed Unc. Throws males. hlh-2(bx115) has no phenotype in this background.

Homozygous lethal deletion chromosome balanced by bli-4- and GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP n5287 homozygotes (embryonic lethal). Homozygous hT2 [bli-4 let-? qIs48] inviable. Pick wild-type GFP and check for correct segregation of progeny to maintain. n5287 is a 2,694 bp deletion (flanking seq 5' - TGCAACTGCCGCCATTGCTC 3' - AAAACTCTCTAGCATATTGT) and 25 bp insertion (TCTGCCATCATTGCTGCCATTGCTC).

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).
