ARL8B
ARF like GTPase 8B | FLJ10702, Gie1, ARL10C

Enables G protein activity; guanyl ribonucleotide binding activity; and tubulin binding activity. Involved in several processes, including antigen processing and presentation following phagocytosis; cytosolic transport; and vesicle fusion. Located in cytolytic granule membrane; midbody; and spindle midzone. Is active in early endosome membrane and lysosomal membrane. [provided by Alliance of Genome Resources, Jul 2025]

ARL8B — as a Regulated Gene

TFs regulating ARL8B 0 TFs

Transcription factors with Perturb-seq knockdown data for ARL8B. 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 = ARL8B 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 ARL8B

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of ARL8B, 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.
