FIS1
fission, mitochondrial 1 | CGI-135, H_NH0132A01.6, TTC11

Enables identical protein binding activity; lipid binding activity; and molecular adaptor activity. Involved in several processes, including negative regulation of ATP metabolic process; negative regulation of fatty acid transport; and organelle fission. Acts upstream of or within mitochondrion organization. Located in mitochondrial outer membrane and peroxisomal membrane. Part of protein-containing complex. Biomarker of Alzheimer's disease.

FIS1 — as a Regulated Gene

TFs regulating FIS1 0 TFs

Transcription factors with Perturb-seq knockdown data for FIS1. 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 = FIS1 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 FIS1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of FIS1, 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.
