Ras-related GTP-binding protein B |
Comment |
FUNCTION:Has guanine nucleotide-binding activity but undetectable intrinsic GTPase activity. Required for the amino acid-induced relocalization of mTORC1 to the lysosomes and its subsequent activation by the GTPase RHEB. This is a crucial step in the activation of the TOR signaling cascade by amino acids. Involved in the RCC1/Ran-GTPase pathway. Involved in the RCC1/Ran-GTPase pathway.||SUBUNIT:The short isoform binds GTP (By similarity). Interacts with RRAGC and RRAGD.||INTERACTION:Q9HB90:RRAGC; NbExp=1; IntAct=EBI-993049, EBI-752390; Q9NQL2:RRAGD; NbExp=1; IntAct=EBI-993049, EBI-992949;||SUBCELLULAR LOCATION:Cytoplasm. Lysosome.||ALTERNATIVE PRODUCTS:Event=Alternative splicing; Named isoforms=2; Name=1; Synonyms=Long; IsoId=Q5VZM2-1; Sequence=Displayed; Name=2; Synonyms=Short; IsoId=Q5VZM2-2; Sequence=VSP 052073;||SIMILARITY:Belongs to the GTR/RAG GTP-binding protein family. |
