EPRS1
glutamyl-prolyl-tRNA synthetase 1 | EARS, GLUPRORS, PARS, EPRS, QARS, QPRS

Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is a multifunctional aminoacyl-tRNA synthetase that catalyzes the aminoacylation of glutamic acid and proline tRNA species. Alternative splicing has been observed for this gene, but the full-length nature and biological validity of the variant have not been determined. [provided by RefSeq, Jul 2008]

EPRS1 — as a Regulated Gene

TFs regulating EPRS1 0 TFs

Transcription factors with Perturb-seq knockdown data for EPRS1. 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 = EPRS1 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 EPRS1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of EPRS1, 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.
