Data are extracted from flyatlas.org,from on tissue-specific Affymetrix microarray experiments(Chintapalli et al., 2007). TRPP (polycystin) has a Drosophila orthologue: Pkd2, which is enriched in testes and sperm. TRPML has no annotated Drosophilaorthologue (Flybase). *Three different datasets based on three distinct Affymetrix probe sets for CG34123-significant enrichment for tubule is seen with all three probes. Data in brackets are for larval tubule. TRP, transient receptor protein
