Immunohistochemistry (Frozen sections) - Anti-mTOR (phospho S2448) antibody [EPR426(2)] (AB109268)
IHC image of mTOR (phospho S2448) staining in a section of frozen normal human heart performed on a Leica BONDTM system using the standard protocol. The section was fixed in 10% paraformaldehyde (10 min) prior to staining. The section was incubated with ab109268, 1/200 dilution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

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.
