Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, Balb/3T3 mouse embryonic fibroblast cell line, NRK rat normal kidney cells, and PC-12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 1 µg/mL Mouse Anti-Human/Mouse/Rat MP1 Monoclonal Antibody (Catalog # MAB4367) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, recombinant human MP1 (2 ng) was included. A specific band for MP1 was detected at approximately 14 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

Background: MP1

MP1 (MEK Partner 1), gene name LAMTOR3 (late endosomal/lysosomal adaptor and MAPK and MTOR activator 3), was initially identified as a scaffold protein that tethers MEK1 and ERK1 to facilitate their activation. MP1 and other MAPK scaffolds promote phosphorylation efficiency and specificity, localize their bound pathway components to particular subcellular sites, and serve as nodes of signal integration for regulation of MAPK pathways by other signaling events. With the assistance of adaptor protein p14, the bound MP1 complex localizes to late endosomes and is thought to regulate endosomal traffic and cellular proliferation during tissue homeostasis.
