The application of rapid evaporative ionization mass spectrometry in the analysis of Drosophila species-a potential new tool in entomology. Open Biol. 33234068 FBrf0247327
Here we introduce TEchim, a new software that extracts chimeric sequencing reads that span transposon-gene breakpoints. In addition, we introduce scHardyWeinberg, a new approach to quantify co-expression levels in high-throughput single-cell sequencing data. Transposon expression in the Drosophila brain is driven by neighboring genes and diversifies the neural transcriptome. Genome Res. 32973040 FBrf0247119

Dominant negative form of IP3R protein. It has three mutated amino acids which prevent ligand binding. IP3R being tetramer, requires IP3 binding to all monomers. Hence presence of even single IP3R-DN monomer in tetramer can render whole IP3R protein complex functionless. Modulation of flight and feeding behaviours requires presynaptic IP3Rs in dopaminergic neurons. eLife 33155978 FBrf0247160
