For MXE validation, at least three restraints must be fulfilled: the absence of an MXE‐joining read (R1), except for those leading to frame shift, and the presence of two MXE‐bridging SJ reads (R2 and R3). Mutually exclusive splicing is a regulated means to generate protein diversity, but the underlying mechanisms are poorly understood. Mutually exclusive splicing is a unique and challenging model that can be used to elucidate the evolution, regulatory mechanism, and function of alternative splicing. Alternative splicing of pre-mRNA is a major mechanism to increase protein diversity in higher eukaryotes. This is not entirely surprising, however, since multiple, distinct mechanisms are known to exist to guarantee that only one exon is included when only two alternative exons need to be chosen from. The 18 mammals, their phylogenetic relation and the total numbers of MXEs shared with human are presented at the bottom. The column bar graph summarizes counts where the SNP‐containing MXE is 1.5‐fold more expressed than the non‐SNP‐containing MXE, whereas the row bar graph shows this for each tissue, cell type and developmental stage.

The structural impacts … The CUX1 gene (cut‐like homeobox 1) contains two interleaved clusters of MXEs (clusters 1 and 2) and two standard clusters each with two MXEs (clusters 3 and 4). This mutually exclusive behavior is enforced by absolute incompatibility between the adjacent splice sites of the two exons, due to close proximity of the exon 3 branch point to exon 2. Cells have to make a lot of proteins in order to function right. Accordingly, 87% of the MXE‐encoded protein regions are embedded in secondary structural elements (orange and green symbols), and most of the remaining MXEs can only be spliced mutually exclusive because splicing as differentially included exons would lead to frame shifts (blue circles). We propose a new method, ESTs-To-ESRs (E2E), that uses splicing graphs from the Drosophila melanogaster Exon Database (DEDB) to identify mutually exclusive (ME) exons and subsequently finds putative ESR motifs by looking for conserved fragments in a multiple alignment of these ME exons. MXE ‐ratio expression predicts disease…, Figure 4. Mutually exclusive splicing of exons is a mechanism of functional gene and protein diversification with pivotal roles in organismal development and diseases such as Timothy syndrome, cardiomyo-pathy and cancer in humans.

Furthermore, the identification of long-range RNA secondary structures provides a mechanistic framework for the regulation of mutually exclusive splicing (i.e., Dscam splicing). Dscam; RNA secondary structure; high-throughput sequencing; mechanism; mutually exclusive splicing; regulation. This suggests that multiple distinct and independent mechanisms to ensure the mutually exclusive splicing of clusters of three or more exons may have evolved multiple times.

Prevention and treatment information (HHS). As the name “mutually exclusive” indicates, exactly one out of two exons (or one group out of two exon groups) is retained, while the other one is spliced out. The use of new approaches has not only greatly expanded the mutually exclusive exome, but has also enabled the systematic analyses of single-cell alternative splicing during development. Competing RNA secondary structures are required for mutually exclusive splicing of the Dscam exon 6 cluster. Careers. View source: R/Script_01_2_ComputePSI_MXE.R.

In order to obtain a first genomewide estimate of the extent and biological role of mutually exclusive splicing in humans, we predicted and subsequently validated mutually exclusive exons (MXEs) using 515 publically available RNA-Seq datasets. Mutually exclusive splicing (ME) distinguishes itself from classical cassette exon splicing in that ME exons are never observed together in a given cell/tissue. As examples, we labelled many MXE clusters distinguishing annotated MXEs (purple letters), known exons that we validated as MXEs (orange letters), and clusters containing novel exons (dark‐grey letters). The most prevalent pattern of alternative splicing in vertebrates and invertebrates is exon skipping. Dong H, Li L, Zhu X, Shi J, Fu Y, Zhang S, Shi Y, Xu B, Zhang J, Shi F, Jin Y. Long-range RNA pairings contribute to mutually exclusive splicing. Pohl M, Bortfeldt RH, Grützmann K, Schuster S. Biosystems. Biochem Soc Trans.

The tightly regulated production of distinct erythrocyte protein 4.1R isoforms involves differential splicing of 3 mutually exclusive first exons (1A, 1B, 1C) to the alternative 3' splice sites (ss) of exon 2'/2. For each MXE cluster, the per cent‐spliced‐in (PSI) value of the ubiquitous MXE (minimum Gini index) is subtracted from the PSI value of the specific MXE (maximum Gini index of cluster) (delta PSI value) and scaled between −1 (broad tissue distribution) and 1 (highly tissue specific).
