This gene encodes a LIN-28 family RNA-binding protein that acts as a posttranscriptional regulator of genes involved in developmental timing and self-renewal in embryonic stem cells. The encoded protein functions through direct interaction with target mRNAs and by disrupting the maturation of certain miRNAs involved in embryonic development. This protein prevents the terminal processing of the LET7 family of microRNAs which are major regulators of cellular growth and differentiation. Aberrant expression of this gene is associated with cancer progression in multiple tissues. [provided by RefSeq, Sep 2015]
Modules significantly affected by knockdown. ↑ Up = module upregulated upon KD; ↓ Down = module downregulated upon KD.

Genes likely regulated by LIN28A through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to LIN28A knockdown, with negative coefficients indicating downregulation and positive coefficients indicating upregulation upon knockdown.
Open chromatin elements (ATAC-seq) where LIN28A has ChIP-seq or motif footprint binding evidence and which are linked to at least one target gene region.
| Element | Size | Linked genes |
|---|
Transcription factors with Perturb-seq knockdown data for LIN28A. The Binding column indicates whether any binding evidence exists for this TF–gene pair (ChIP-seq or motif footprint peaks). The Mean coef is the average Perturb-seq regression coefficient across active gRNAs (positive = LIN28A upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.
| TF | Mean coef | Binding | Outlier | TF→Gene link |
|---|
Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of LIN28A, linked by TSS proximity or chromatin conformation (Multiome / HiCAR). Each element overlaps at least one TF ChIP-seq binding site — the TFs column shows how many distinct TFs bind that element.
