Enables phosphatidylinositol 3-kinase inhibitor activity. Involved in negative regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction. Predicted to be located in plasma membrane. Predicted to be active in extracellular space. [provided by Alliance of Genome Resources, Jul 2025]
Transcription factors with Perturb-seq knockdown data for PIK3IP1. 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 = PIK3IP1 upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.
| TF | Mean coef | Binding | Outlier | TF→Gene link |

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of PIK3IP1, 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.
| Accessibility | Element | Dist. to TSS | Link type | TFs |
|---|---|---|---|---|
| chr22:31,290,525–31,291,372 | at TSS | At TSS | 818 | |
| chr22:31,292,305–31,292,658 | 1.6 kb | Proximal (<10kb) | 503 |
Genomic view of the PIK3IP1 locus showing ATAC-seq accessibility and RNA-seq expression across the ESC → DE time course, together with TF binding peaks and element-to-TSS loop connections.
