In diploid organisms, biallelic gene expression enables the production of adequate levels of mRNA. This is essential for haploinsufficient genes, which require biallelic expression for optimal function to prevent the onset of developmental disorders. Whether and how a biallelic or monoallelic state is determined in a cell-type-specific manner at individual loci remains unclear.

We describe steps for poly(A) RNA isolation, library preparation, and cDNA size selection. We then detail procedures for sequencing and processing and a computational framework to identify exon couplings and assign mRNA 5' ends and 3' ends to each other.

Here, we assess the regulatory relationships between transcription initiation, alternative splicing, and 3' end site selection. Applying long-read sequencing to accurately represent even the longest transcripts from end to end, we quantify mRNA isoforms in Drosophila tissues, including the transcriptionally complex nervous system.
