Knock-out allele ok237 is a large (2229-bp) deletion. Coordinates: leftmost deleted base = 35441 of K02G10; rightmost deleted base = 296 of F55D10. ok237 eliminates almost all of K02G10.8 (dnj-14) and also the 5'-part of F55D10.3 (glit-1, encodes a homolog of gliotactin), as well as the presumed promoter regions between the 2 genes. In addition, F55D10.3 could be the first member of an operon, with F55D10.2 (aka rpl25.1, which encodes a ribosomal protein) as the second member of the operon. The deletion is likely to eliminate the expression of 2 or 3 genes, not just dnj-14.

F55D10.3, K02G10.8. Apparent homozygous lethal deletion chromosome balanced by lon-2-marked translocation. Heterozygotes are WT, and segregate WT, Lon-2 males, arrested szT1 aneuploids, and ok237 homozygotes (arrest stage/phenotype undetermined). Pick WT and check for correct segregation of progeny to maintain. External left primer: AGTGTTCGGTAAGCATTGGG. External right primer: AAAGTGTGTTCCGTCCTTGG. Internal left primer: CTGCCGTGGAATCTACCTGT. Internal right primer: GCAGTCGAACAACCACTTCA. Internal WT amplicon: 3216 bp. Deletion size: 2229 bp. Deletion left flank: TTTTGAGAAGGCGGTGGAGGCATGGCAATC. Deletion right flank: TTCGCTAAAAAATTGAGCCAATTTATTATT.
