CG41561, a new protein-coding gene on the D. melanogaster Y chromosome. a Intron/exon structure of CG41561 (grey are non-coding exons, green are coding exons). b Mapping of five male (blue) and five female (red) Drosophila genomic reads to CG41561 (for strain information see Supplementary Table 2). c Expression profile of CG41561 across developmental stages (top; samples are ordered by developmental time) and larval and adult tissues (bottom); colors in heatmap refer to expression level. CG41561 is first expressed in third instar larvae, and shows maximum expression in pupae and young adult males (it is not expressed in females). Across tissues, CG41561 is expressed in imaginal discs of third instar larvae and most highly in adult male testis. Expression profiles are taken from flybase.
