ALDH1A3
aldehyde dehydrogenase 1 family member A3 | RALDH3, ALDH6

This gene encodes an aldehyde dehydrogenase enzyme that uses retinal as a substrate. Mutations in this gene have been associated with microphthalmia, isolated 8, and expression changes have also been detected in tumor cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

ALDH1A3 — as a Regulated Gene

TFs regulating ALDH1A3 0 TFs

Transcription factors with Perturb-seq knockdown data for ALDH1A3. 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 = ALDH1A3 upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.

Elements linked to ALDH1A3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of ALDH1A3, 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.
