Anti-LAMTOR1

0.5mg/ml if reconstituted with 0.2ml sterile DI water. Late endosomal/lysosomal adaptor, MAPK and MTOR activator 1 is a protein that in humans is encoded by the LAMTOR1 gene. mTORC1 kinase complex is a critical component in the regulation of cell growth. Its activity is modulated by energy levels, growth factors, and amino acids. The four related GTPases, RagA, RagB, RagC, and RagD, have been shown to interact with raptor in mTORC1. These interactions are both necessary and sufficient for mTORC1 activation in response to amino acid signals. A protein complex consisting of LAMTOR1/C11orf59, LAMTOR2/ROBLD3, and LAMTOR3/MAPKSP1 has been identified to interact with and recruit the four Rag GTPases to the surface of lysosomes. Protein function: As part of the Ragulator complex it is involved in amino acid sensing and activation of mTORC1, a signaling complex promoting cell growth in response to growth factors, energy levels, and amino acids. Activated by amino acids through a mechanism involving the lysosomal V- ATPase, the Ragulator functions as a guanine nucleotide exchange factor activating the small GTPases Rag. Activated Ragulator and Rag GTPases function as a scaffold recruiting mTORC1 to lysosomes where it is in turn activated. LAMTOR1 is directly responsible for anchoring the Ragulator complex to membranes. Also required for late endosomes/lysosomes biogenesis it may regulate both the recycling of receptors through endosomes and the MAPK signaling pathway through recruitment of some of its components to late endosomes. May be involved in cholesterol homeostasis regulating LDL uptake and cholesterol release from late endosomes/lysosomes. May also play a role in RHOA activation. Involved in the control of embryonic stem cells differentiation, together with FLCN it is necessary to recruit and activate RRAGC/RagC and RRAGD/RagD at the lysosomes, and to induce exit of embryonic stem cells from pluripotency via non-canonical, mTOR- independent TFE3 inactivation.
