Gene or accession: CG7075 Gene annotation error I have new supporting evidence or functional assignment for gene CG7075. Comments: This gene's product has been the subject of the Ph.D. thesis of Dora Bigler (1994) at the University of Zürich. By developmental Northern blotting, the gene is expressed only in the testes. Using antibodies prepared against a peptide from the predicted sequence, she showed that the protein appears to be localized to the nucleus in premeiotic spermatocytes, then in the nebenkern and mitochondrial derivatives of postmeiotic spermatocytes. No mutants have yet been identified.
