Summary (written by the submitters)
The SP/KLF family of transcription factors harbour three C-terminal C2H2 zinc fingers interspersed by two linkers which confers DNA-binding to a 9-10bp motif. Mutations in KLF1, the founding member of the family, are common. Missense mutations in linker two result in a mild phenotypes. However, when co-inherited with loss-of-function mutations, they result in severe non-spherocytic hemolytic anemia.

We generated a mouse model of this disease by crossing Klf1+/- mice with Klf1H350R/+ mice that harbour a missense mutation in linker-2. Klf1H350R/- mice exhibit severe hemolysis without thalassemia. RNA-seq demonstrated loss of expression of genes encoding transmembrane and cytoskeletal proteins, but not globins. ChIP-seq showed no change in DNA-binding specificity, but a global reduction in affinity, which was confirmed using recombinant proteins and in vitro binding assays. This study provides new insights into how linker mutations in zinc finger transcription factors result in different phenotypes to those caused by loss-of-function mutations.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

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 GSE94351_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA369423 and SRA study SRP098659. Searching any of these in the dataset finder brings you back here.

Study design
3 × KLF1 +/- mRNAseq vs 3 × KLF1 D45/- mRNAseq vs 3 × KLF1 -/- mRNAseq

Supports a between-group comparison across 9 samples.

How we read this: 3 replicated groups read from 13 sample titles; they account for 9 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
