NCBI and Uniprot Product Information
Uniprot Description
Phosphatidylinositol 3-kinase homolog, component of TORC1, which regulates multiple cellular processes to control cell growth in response to environmental signals. Nutrient limitation and environmental stress signals cause inactivation of TORC1. Active TORC1 positively controls ribosome biogenesis via control of rRNA, ribosomal protein and tRNA gene expression, and rRNA processing. TORC1 positively controls protein biosynthesis by regulation of mRNA stability, translation initiation factor activity, and high-affinity amino acid permeases that serve to provide amino acids for use by the translation machinery. TORC1 also promotes growth by sequestering a number of nutrient and general stress-responsive transcription factors in the cytoplasm. TORC1 negatively controls macroautophagy, a process to recycle surplus cytoplasmic mass under nutrient starvation conditions. TORC1 controls many of these processes via TIP41-TAP42-mediated inhibition of the type 2A-related phosphatases PP2A and SIT4 (PubMed:10198052, PubMed:10329624, PubMed:10604478, PubMed:10995454, PubMed:11741537, PubMed:15620355, PubMed:7606777, PubMed:8741837, PubMed:9539725, PubMed:9843498). In nutrient rich conditions, responsible for the phosphorylation of AGC S6 kinase (S6K) YPK3, activating YPK3 kinase activity and promoting phosphorylation of ribosomal protein S6 (PubMed:25767889). Phosphorylates kinase SCH9 at 6 amino acids in the C-terminus, activating SCH9 kinase activity to properly regulate ribosome biogenesis, translation initiation, and entry into stationary phase (PubMed:17560372).

Product Notes
The TOR1 tor1 (Catalog #AAA1128903) is a Recombinant Protein produced from E Coli or Yeast or Baculovirus or Mammalian Cell and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Serine/threonine-protein kinase TOR1 (TOR1), Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
