NCBI and Uniprot Product Information
NCBI Description
This gene encodes a scaffold protein that functions in the extracellular signal-regulated kinase (ERK) cascade. The protein is localized to late endosomes by the mitogen-activated protein-binding protein-interacting protein, and binds specifically to MAP kinase kinase MAP2K1/MEK1, MAP kinase MAPK3/ERK1, and MAP kinase MAPK1/ERK2. Studies of the orthologous gene in mouse indicate that it regulates late endosomal traffic and cell proliferation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. A pseudogene of this gene is located on the long arm of chromosome 13.

Uniprot Description
LAMTOR3: Regulator of the TOR pathway, a signaling cascade that promotes cell growth in response to growth factors, energy levels, and amino acids. As part of the Ragulator complex, recruits the Rag GTPases and the mTORC1 complex to lysosomes, a key step in activation of the TOR signaling cascade by amino acids. Adapter protein that enhances the efficiency of the MAP kinase cascade facilitating the activation of MAPK2. Interacts with MAP2K1/MEK1 and MAPK2. Interacts with MORG1. Part of the Ragulator complex composed of LAMTOR1, LAMTOR2 and LAMTOR3. Interacts with LAMTOR1; the interaction is direct. Belongs to the LAMTOR3 family.

Product Notes
The MK1I1 lamtor3 (Catalog #AAA9418117) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The MK1I1 Antibody reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's MK1I1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Western Blot: 1:500-1:2000. Researchers should empirically determine the suitability of the MK1I1 lamtor3 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "MK1I1, Polyclonal Antibody" 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
