PNPLA3
patatin like domain 3, 1-acylglycerol-3-phosphate O-acyltransferase | FLJ22012, adiponutrin, dJ796I17.1, iPLA2epsilon, ADPN, C22orf20

The protein encoded by this gene is a triacylglycerol lipase that mediates triacylglycerol hydrolysis in adipocytes. The encoded protein, which appears to be membrane bound, may be involved in the balance of energy usage/storage in adipocytes. [provided by RefSeq, Jul 2008]

PNPLA3 — as a Regulated Gene

TFs regulating PNPLA3 0 TFs

Transcription factors with Perturb-seq knockdown data for PNPLA3. 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 = PNPLA3 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 PNPLA3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of PNPLA3, 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.
