Enables G protein activity and amino acid sensor activity. Involved in COPII-coated vesicle budding; cellular response to leucine starvation; and negative regulation of TORC1 signaling. Is active in COPII vesicle coat; endoplasmic reticulum exit site; and lysosomal membrane. [provided by Alliance of Genome Resources, Jul 2025]
Transcription factors with Perturb-seq knockdown data for SAR1A. 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 = SAR1A 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 SAR1A, 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.
