Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The mammalian target of rapamycin commonly known as mTOR is a serine/threonine kinase known for its role in cellular growth and metabolism. It has a molecular weight of approximately 289 kDa. mTOR is expressed in various tissues throughout the body including muscle adipose tissue and the brain. The protein functions as a central regulator of cell proliferation protein synthesis and nutrient signaling. Often researchers utilize mTOR ELISA or mTOR western blot (mTOR WB) methods and mTOR antibodies to study its expression and activity in various biological contexts.
Biological function summary

MTOR integrates signals from nutrients growth factors and cellular energy status to maintain cellular homeostasis. It forms part of two distinct complexes mTORC1 and mTORC2 which differ in their component proteins and downstream effects. mTORC1 primarily responds to amino acids and regulates protein synthesis through phosphorylation of key substrates like S6K1. On the other hand mTORC2 is important for maintaining cytoskeletal integrity and cell survival highlighting the protein's importance in diverse cellular processes.

Pathways

MTOR plays a pivotal role in the PI3K/AKT/mTOR pathway which governs cell growth proliferation and survival. It also has implications in the regulation of the AMPK pathway which senses cellular energy levels. Through these pathways mTOR interacts with proteins such as AKT and TSC2. The phospho-mTOR specifically the S2448 phospho-mTOR serves as an important functional marker in these signaling cascades linking extracellular signals to downstream cellular responses.

MTOR has connections to cancer and neurodegenerative diseases. Its dysregulation often leads to uncontrolled cellular proliferation a hallmark of many cancers. Conditions such as tuberous sclerosis can occur due to mutations in proteins like TSC1 and TSC2 that regulate mTOR activity. In Alzheimer's disease mTOR's role in autophagy and protein synthesis becomes significant as imbalance may contribute to disease progression. Understanding these connections highlights the potential of targeting mTOR pathways therapeutically.

Target data

The protein expressed by the MTOR gene is a serine/threonine protein kinase that serves as a central regulator of cellular metabolism, growth, and survival in response to various signals, such as hormones and nutrients. MTOR operates within two distinct signaling complexes, mTORC1 and mTORC2. mTORC1 is activated to upregulate protein synthesis by phosphorylating regulators of mRNA translation and ribosome synthesis, and phosphorylates and activates proteins like RPS6KB1 and RPS6KB2 to promote protein synthesis. It controls MiT/TFE factors TFEB and TFE3 by mediating their retention and inactivation under nutrient-rich conditions, and it inhibits autophagy by phosphorylating DAP and RUBCNL/Pacer. Additionally, mTORC1 engages in feedback control on growth factor signaling and may influence microtubules through CLIP1 phosphorylation. The mTORC2 complex may regulate cellular processes, including survival and cytoskeletal organization, by phosphorylating AKT1 and regulating the actin cytoskeleton via PRKCA, PXN, and Rho-type guanine nucleotide exchange factors. It also regulates the phosphorylation of SGK1. This supplementary information is collated from multiple sources and compiled automatically.
