LPCAT4
lysophosphatidylcholine acyltransferase 4 | FLJ10257, LPAAT-eta, LPEAT2, LPLAT10, AGPAT7, AYTL3

Members of the 1-acylglycerol-3-phosphate O-acyltransferase (EC 2.3.1.51) family, such as AGPAT7, catalyze the conversion of lysophosphatidic acid (LPA) to phosphatidic acid (PA), a precursor in the biosynthesis of all glycerolipids. Both LPA and PA are involved in signal transduction (Ye et al., 2005 [PubMed 16243729]).[supplied by OMIM, May 2008]

LPCAT4 — as a Regulated Gene

TFs regulating LPCAT4 0 TFs

Transcription factors with Perturb-seq knockdown data for LPCAT4. 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 = LPCAT4 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 LPCAT4

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of LPCAT4, 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.
