Pyd isoforms and protein domains. Scheme of some relevant pyd transcripts (adapted from flybase GBrowse) and protein isoforms showing the position of novel generated mutations (red triangles), the region targeted by the UAS-RNAi 9763R-2, and the position of the protein regions used as epitopes to raise specific antibodies. The gray columns approximately indicate coding exons, and the lines show the equivalence between exons and protein domains. Predicted isoforms Pyd-A to Pyd-C are enriched in wing discs and Pyd-P in nephrocytes.
