Mtor and raptor
WebThe role of the mTORC1 complex, which is based on the interaction between mTOR and Raptor (regulatory associated protein of mTOR), is responsible for activating the downstream substrates, S6K1 and 4E-BP1. The role of the mTORC2 complex, which is based on the interaction between mTOR and Rictor (rapamycin-insensitive companion of … WebThe existence of separable mTOR pathways in adipocytes helps to explain conflicting results in the literature on the role of mTOR in adipocyte browning. Loss of raptor and mTORC1 activity in fat leads to browning of WAT (Polak et al. 2008; Tran et al. 2016), while converse activation of mTOR via deletion of TSC1 leads to whitening of BAT (Xiang ...

WebThe mechanistic target of rapamycin (MTOR) is a giant protein kinase that, together with the accessory proteins Raptor and mLst8, forms a complex of over 1 MDa known as MTOR … Web26 iul. 2002 · The mTOR-raptor interaction also regulates the kinase activity of mTOR and is sensitive to conditions, such as nutrient availability, that signal through the pathway. Thus, we provide a mechanism for how nutrients regulate mTOR activity in vivo. Although rapamycin has been regarded as mimicking the effects of nutrient deprivation, we find …

Regulatory-associated protein of mTOR (Raptor)-deficient alveolar macrophages, which do not have active mTORC1 (Fig. 1), display a strong reduction in glucose uptake. WebRaptor is the defining component of what we now call mTOR complex 1 (mTORC1) (Fig. 1A). We went on to identify the other components of mTORC1: DEPTOR, PRAS40, and …

WebBackground. The regulatory associated protein of mTOR (Raptor) was identified as an mTOR binding partner that mediates mTOR signaling to downstream targets (1,2). Raptor binds to mTOR substrates, including 4E-BP1 and p70 S6 kinase, through their TOR signaling (TOS) motifs and is required for mTOR-mediated phosphorylation of these … farther-flungWeb1 ian. 2006 · FLAG-tagged raptor, mTOR, and a 90-kDa protein (p90) are indicated by arrows.
