Tempus Gene Library
This gene overview is brought to you as part of Tempus’ goal to inform providers about our genomic testing panels and the genes included in our offerings. Through our robust de-identified database of clinical information coupled with molecular testing results, we are capable of providing unique insights into these gene alterations. Many of the gene alterations reported on our somatic and germline panels are often key inclusion criteria for clinical trials.
mTOR Gene
Mammalian Target of RapamycinThe mTOR gene encodes a phosphatidylinositol serine/threonine kinase protein that functions in response to DNA damage and nutrient deprivation. It is part of the mTORC1 and mTORC2 signaling complexes that regulate translation, and its function in the PI3K-AKT-mTOR signaling pathway regulates cellular proliferation and survival. Activating mutations and overexpression of mTOR are associated with cancer progression.
