Paper: Manipulation of Alternative Splicing of IKZF1 Elicits Distinct Gene Regulatory Responses in T CellsCells · 2026

Summary (written by the submitters)

Genome-wide association studies have identified statistically significant associations between genetic variants in or near the IKZF1 gene and several autoimmune disorders. IKZF1, encoding the transcription factor Ikaros, produces at least 10 distinct transcripts via alternative splicing. To explore the role of alternative splicing of IKZF1 in mature T cells, we generated a panel of Jurkat T-cell clones with various truncating mutations in IKZF1 exon 4, exon 6 or both.

Differences among clones in gene expression, chromatin accessibility, and protein abundance were assessed by RNA-seq, ATAC-seq and immunoblotting. Clones with single targeting events in either exon 4 or 6 clustered separately from double-targeted clones on multiple parameters, but overall, clone responses were highly heterogeneous. Perturbation of IKZF1 splicing resulted in significant differences in expression and chromatin accessibility of other autoimmunity-associated genes and elicited compensatory expression changes in other IKZF family members. Our results suggest that even modest perturbations of IKZF1 splicing can have significant effects on gene expression and function in mature T cells.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE252707_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1062296 and SRA study SRP482544. Searching any of these in the dataset finder brings you back here.
