AP2A2
adaptor related protein complex 2 subunit alpha 2 | DKFZP564D1864, HIP9, HYPJ, KIAA0899, ADTAB, CLAPA2

The protein encoded by this gene is a subunit of the AP-2 adaptor protein complex, which is involved in linking lipid and protein membrane components with the clathrin lattice. This interaction supports the formation of clathrin-coated vesicles, and the encoded subunit aids in the process by binding polyphosphoinositide-containing lipids in the cell membrane.

AP2A2 — as a Regulated Gene

TFs regulating AP2A2 0 TFs

Transcription factors with Perturb-seq knockdown data for AP2A2. 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 = AP2A2 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 AP2A2

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of AP2A2, 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.
