Description

Sequence encoding amino acids 1-13 of Ctr1C have been replaced with the EGFP open reading frame followed by an SV40 polyA sequence and several stop codons. This allows expression of EGFP under the control of Ctr1C regulatory sequences. Expression of the residual Ctr1C ORF is unlikely due to the presence of the SV40 polyA sequence and the stop codons.

Statement
Reference

Although 12 day old mutant Ctr1B3-4 males are fertile, Ctr1B3-4 Ctr1C6D double mutant males display almost complete sterility, indicating that in the absence of Ctr1B, Ctr1C is required for male fertility. These males are only partially sterile before this time however. Testes at any age do not reveal obvious morphological differences compared to control males. If Ctr1B3-4 Ctr1C6D double mutant males are kept on food supplemented with copper after eclosion, i.e. as adult flies, for 12 days, fertility is largely restored. Fertility is also restored by the presence of Ctr1CT:Avic\GFP-EGFP, Ctr1C+t8 or Ctr1BT:Avic\GFP.
