Product Overview

Description	Recombinant Human Mitogen-Activated Protein Kinase Scaffold Protein 1 is produced by our E.coli expression system and the target gene encoding Met1-Ser124 is expressed with a 6His tag at the N-terminus.
Accession	Q9UHA4
Synonym	Ragulator Complex Protein LAMTOR3; Late Endosomal/Lysosomal Adaptor and MAPK and MTOR Activator 3; MEK-Binding Partner 1; Mp1; Mitogen-Activated Protein Kinase Kinase 1-Interacting Protein 1; Mitogen-Activated Protein Kinase Scaffold Protein 1; LAMTOR3; MAP2K1IP1; MAPKSP1
Gene Background	Mitogen-Activated Protein Kinase Scaffold Protein 1 (MAPKSP1) was identified as an interacting protein that belongs to the LAMTOR3 family. MAPKSP1 restricted 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. MAPKSP1 interacts with MAP2K1/MEK1 and MAPK2 and enhances the activation of MAPK2, and thus is thought to function as an adaptor to enhance the efficiency of the MAP kinase cascade.

Target Details

Target Function	As part of the Ragulator complex it is involved in amino acid sensing and activation of mTORC1, a signaling complex promoting cell growth in response to growth factors, energy levels, and amino acids. Activated by amino acids through a mechanism involving the lysosomal V-ATPase, the Ragulator functions as a guanine nucleotide exchange factor activating the small GTPases Rag. Activated Ragulator and Rag GTPases function as a scaffold recruiting mTORC1 to lysosomes where it is in turn activated. Adapter protein that enhances the efficiency of the MAP kinase cascade facilitating the activation of MAPK2.
Subcellular Location	Late endosome membrane; Peripheral membrane protein; Cytoplasmic side.
Protein Families	LAMTOR3 family

Interfering with the MEK1/MP1/ERK1 axis using a MEK1 inhibitor or MP1 depletion repressed BCL2 expression and sensitized MLCCs to chemoradiotherapy. PMID: 28606806 The present study was aimed at investigating whether the miR-29c binding site single nucleotide polymorphisms within the 3'-UTRs of LAMTOR3 gene affected the gastric cancer risk. PMID: 25661340 we demonstrate that the MAPK scaffold protein MEK partner 1 (MP1) is important for gastrin-induced phosphorylation of ERK1 and ERK2 and that MP1 promotes gastrin-induced proliferation of AGS-GR cells PMID: 23408059 identified polymorphisms in LAMTOR2 and LAMTOR3 do not seem to play a relevant role in breast cancer PMID: 23341997 A complex encoded by the MAPKSP1, ROBLD3, and c11orf59 genes interacts with the Rag GTPases, recruits them to lysosomes, and is essential for mTORC1 activation PMID: 20381137 We investigated the neuroprotective effect of glial-derived neurotrophic factor (GDNF) upon alcohol-exposed B92 cultures, as well as the role of the cytoskeleton and mitogen-activated protein kinase (MAPK) pathways in this effect.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
