"DCP-1, a Drosophila cell death protease essential for development" by Z. Song et al. (24 Jan. 1997, p. 536) and "Requirement for DCP-1 caspase during Drosophila oogenesis" by K. McCall and H. Steller (9 Jan. 1998, p. 230). Annotation of the Drosophila genome <up>M. D. Adams et al., Science287, 2185 (2000)</up> has shown that the dcp-1 gene is located within an intron of another gene, CG3941. P-element alleles of dcp-1 described in these two papers also disrupt expression of CG3941. Several phenotypes that were previously attributed to loss of dcp1, including melanotic tumors, small imaginal discs, and dumpless egg chambers, have now been shown to be due to disruption of CG3941 <up>B. Laundrie et al., Genetics 165, 1884 (2003)</up>. However, single mutations in dcp-1 show defective germline cell death, and loss of dcp-1 contributes to the ovary phenotype previously reported for the P-element alleles. Thus, the original ovary phenotype reported for the P-element alleles was due to the combined loss of dcp-1 and CG3941. The role of dcp-1 in somatic cell death is currently under investigation.
