LAMTOR1
late endosomal/lysosomal adaptor, MAPK and MTOR activator 1 | FLJ20625, Pdro, Ragulator1, p18, p27RF-Rho, C11orf59

Enables GTPase binding activity and protein-membrane adaptor activity. Contributes to guanyl-nucleotide exchange factor activity and molecular adaptor activity. Involved in several processes, including cholesterol homeostasis; positive regulation of TORC1 signaling; and regulation of cholesterol transport. Located in lysosome. Part of FNIP-folliculin RagC/D GAP. Is active in Ragulator complex and lysosomal membrane. [provided by Alliance of Genome Resources, Apr 2025]

LAMTOR1 — as a Regulated Gene

TFs regulating LAMTOR1 0 TFs

Transcription factors with Perturb-seq knockdown data for LAMTOR1. 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 = LAMTOR1 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 LAMTOR1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of LAMTOR1, 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.
