CC -!- FUNCTION: As part of the Ragulator complex it is involved in amino acid
CC sensing and activation of mTORC1, a signaling complex promoting cell
CC growth in response to growth factors, energy levels, and amino acids.
CC Activated by amino acids through a mechanism involving the lysosomal V-
CC ATPase, the Ragulator functions as a guanine nucleotide exchange factor
CC activating the small GTPases Rag. Activated Ragulator and Rag GTPases
CC function as a scaffold recruiting mTORC1 to lysosomes where it is in
CC turn activated. When complexed to BIRC5, interferes with apoptosome
CC assembly, preventing recruitment of pro-caspase-9 to oligomerized
CC APAF1, thereby selectively suppressing apoptosis initiated via the
CC mitochondrial/cytochrome c pathway. {ECO:0000250|UniProtKB:O43504}.
CC -!- SUBUNIT: Homodimer. Part of the Ragulator complex composed of LAMTOR1,
CC LAMTOR2, LAMTOR3, LAMTOR4 and LAMTOR5. LAMTOR4 and LAMTOR5 form a
CC heterodimer that interacts, through LAMTOR1, with a LAMTOR2, LAMTOR3
CC heterodimer. The Ragulator complex interacts with both the mTORC1
CC complex and heterodimers constituted of the Rag GTPases RRAGA, RRAGB,
CC RRAGC and RRAGD; regulated by amino acid availability. The Ragulator
CC complex interacts with SLC38A9; the probable amino acid sensor.
CC Component of the lysosomal folliculin complex (LFC), composed of FLCN,
CC FNIP1 (or FNIP2), RRAGA/RagA or RRAGB/RagB GDP-bound, RRAGC/RagC or
CC RRAGD/RagD GTP-bound, and Ragulator. Interacts with phosphorylated
CC BIRC5; the resulting complex binds pro-caspase-9, as well as active
CC caspase-9, but much less efficiently. Interacts with SUPV3L1.
CC {ECO:0000250|UniProtKB:O43504}.
CC -!- SUBCELLULAR LOCATION: Lysosome {ECO:0000250|UniProtKB:O43504}.
CC Cytoplasm, cytosol {ECO:0000250|UniProtKB:O43504}.
CC -!- SIMILARITY: Belongs to the LAMTOR5 family. {ECO:0000305}.
