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 (By similarity). {ECO:0000250|UniProtKB:Q0VGL1}.
CC   -!- SUBUNIT: Part of the Ragulator complex composed of LAMTOR1, LAMTOR2,
CC       LAMTOR3, LAMTOR4 and LAMTOR5. LAMTOR4 and LAMTOR5 form a heterodimer
CC       that interacts, through LAMTOR1, with a LAMTOR2, LAMTOR3 heterodimer.
CC       The Ragulator complex interacts with both the mTORC1 complex and
CC       heterodimers constituted of the Rag GTPases RRAGA, RRAGB, RRAGC and
CC       RRAGD; regulated by amino acid availability. The Ragulator complex
CC       interacts with SLC38A9; the probable amino acid sensor. Component of
CC       the lysosomal folliculin complex (LFC), composed of FLCN, FNIP1 (or
CC       FNIP2), RRAGA/RagA or RRAGB/RagB GDP-bound, RRAGC/RagC or RRAGD/RagD
CC       GTP-bound, and Ragulator. {ECO:0000250|UniProtKB:Q0VGL1}.
CC   -!- SUBCELLULAR LOCATION: Lysosome {ECO:0000250|UniProtKB:Q0VGL1}.
CC   -!- SIMILARITY: Belongs to the LAMTOR4 family. {ECO:0000305}.
