Summary
NPRL3 (NPR3 like, GATOR1 complex subunit, HGNC:14124) is a protein-coding gene on chromosome 16p13.3, encoding GATOR1 complex protein NPRL3 (Q12980). As a component of the GATOR1 complex functions as an inhibitor of the amino acid-sensing branch of the mTORC1 pathway. It is haploinsufficient (ClinGen: sufficient evidence).
Predicted to enable GTPase activator activity. Involved in cellular response to amino acid starvation and negative regulation of TORC1 signaling. Part of GATOR1 complex. Is active in lysosomal membrane. Implicated in familial focal epilepsy with variable foci 3.

Function. As a component of the GATOR1 complex functions as an inhibitor of the amino acid-sensing branch of the mTORC1 pathway. In response to amino acid depletion, the GATOR1 complex has GTPase activating protein (GAP) activity and strongly increases GTP hydrolysis by RagA/RRAGA (or RagB/RRAGB) within heterodimeric Rag complexes, thereby turning them into their inactive GDP-bound form, releasing mTORC1 from lysosomal surface and inhibiting mTORC1 signaling. In the presence of abundant amino acids, the GATOR1 complex is negatively regulated by GATOR2, the other GATOR subcomplex, in this amino acid-sensing branch of the TORC1 pathway.
Subunit / interactions. Within the GATOR complex, component of the GATOR1 subcomplex, made of DEPDC5, NPRL2 and NPRL3. GATOR1 mediates the strong interaction of the GATOR complex with small GTPases Rag (RagA/RRAGA, RagB/RRAGB, RagC/RRAGC and/or RagD/RRAGD) heterodimers. GATOR1 interacts with GPR155/LYCHOS; interaction takes place in presence of cholesterol and prevents interaction between GATOR1 and KICSTOR.
Subcellular location. Lysosome membrane.
Tissue specificity. Widely expressed. Expressed in the frontal lobe cortex as well as in the temporal, parietal, and occipital lobes.
Disease relevance. Inactivating mutations and truncating deletions in the genes encoding GATOR1 proteins are detected in glioblastoma and ovarian tumors and are associated with loss of heterozygosity events. Inactivation of GATOR1 proteins promotes constitutive localization of mTORC1 to the lysosomal membrane and blocks mTORC1 inactivation following amino acid withdrawal. Epilepsy, familial focal, with variable foci 3 (FFEVF3) [MIM:617118] An autosomal dominant form of epilepsy characterized by focal seizures arising from different cortical regions, including the temporal, frontal, parietal, and occipital lobes. Seizure types commonly include temporal lobe epilepsy, frontal lobe epilepsy, and nocturnal frontal lobe epilepsy. Some patients may have intellectual disability or autism spectrum disorders. Seizure onset usually occurs in the first or second decades, although later onset has been reported, and there is phenotypic variability within families. A subset of patients have structural brain abnormalities. Penetrance of the disorder is incomplete. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the NPR3 family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 86 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
