Construct: A truncated kel cDNA fragment (encoding the 76kD ORF1 kel protein) is expressed under the control of an otu promoter (nucleotides 1 to 740 of the genomic sequence in FBrf0050545). The fs(1)K10 3' untranslated region containing transcription termination sequences is fused to the 3' end of the kel cDNA fragment.
Hemizygous kelDE1 flies carrying kelORF1.otu produce eggs at nearly wild-type rates. kelneo2/kelPL25 flies carrying kelORF1.otu produce eggs at approximately wild-type rates.
Nurse cell ring canal diameter in kelDE1 homozygotes is completely rescued by kelORF1.otu.
