What pLDDT means and how to read it

Function

Subunit of both mTORC1 and mTORC2, which regulates cell growth and survival in response to nutrient and hormonal signals (PubMed:12718876, PubMed:15268862, PubMed:15467718, PubMed:24403073, PubMed:28489822). mTORC1 is activated in response to growth factors or amino acids (PubMed:12718876, PubMed:15268862, PubMed:15467718, PubMed:24403073). In response to nutrients, mTORC1 is recruited to the lysosome membrane and promotes protein, lipid and nucleotide synthesis by phosphorylating several substrates, such as ribosomal protein S6 kinase (RPS6KB1 and RPS6KB2) and EIF4EBP1 (4E-BP1) (PubMed:12718876, PubMed:15268862, PubMed:15467718, PubMed:24403073). In the same time, it inhibits catabolic…

Subunit structure

Part of the mechanistic target of rapamycin complex 1 (mTORC1) which contains MTOR, MLST8 and RPTOR (PubMed:12408816, PubMed:12718876, PubMed:15268862, PubMed:17510057, PubMed:23636326, PubMed:24403073, PubMed:26678875, PubMed:27909983, PubMed:28489822, PubMed:29236692, PubMed:31601764, PubMed:34519268, PubMed:34519269, PubMed:36697823). mTORC1 associates with AKT1S1/PRAS40, which inhibits its…
