TRA2-BETA1 (canonical isoform) binds to four enhancers present in exon 2 HsaEX0066781), which activates its inclusion. Inclusion of exon 2 generates mRNAs that are not translated into proteins. HTRA2-BETA1 interacting proteins promote exon 2 skipping by sequestering it, which upregulates the HTRA2-BETA1 protein synthesis. It is proposed that the regulation of the tra2-beta pre-mRNA alternative splicing provides a robust and sensitive molecular sensor that measures the ratio between HTRA2-BETA1 and its interacting proteins.

[CRISPR screen]. Conserved poison exon with mixed impact when depleted: HeLa Enriched at 14 days (FC=1.571, FDR=0.000), PC9 No Change at 14 days (FC=0.954, FDR=0.648), Late Xenograft Depleted (FC=0.512, FDR=0.000).

Poison exons in serine-arginine-rich (SR) proteins, a family of 14 essential SFs, are differentially spliced during induced pluripotent stem cell (iPSC) differentiation and in tumors versus normal tissues. The study uncovers an extensive cross-regulatory network of SR proteins controlling their expression via alternative splicing coupled to nonsense-mediated decay.
