Recombinant human MAPKBP1 (Mitogen-Activated Protein Kinase Binding Protein 1) is a protein encoded by the *MAPKBP1* gene and plays a regulatory role in stress-activated signaling pathways, particularly the c-Jun N-terminal kinase (JNK) pathway. MAPKBP1 acts as a scaffold or co-chaperone, interacting with JNK and other components like MAPK kinases (MAPKKs) to modulate signal transduction. It facilitates the spatial organization and activation of JNK in response to cellular stressors, cytokines, or growth factors, influencing processes such as apoptosis, proliferation, and differentiation. Dysregulation of MAPKBP1 is linked to diseases including cancer and neurodegenerative disorders.
Recombinant MAPKBP1 is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to ensure proper folding and post-translational modifications. It is purified to high homogeneity for functional studies, enabling researchers to dissect its interactions with signaling molecules, structural domains (e.g., JNK-binding regions), and regulatory mechanisms. Applications include *in vitro* kinase assays, protein-protein interaction mapping, and screening for therapeutic agents targeting JNK-related pathways. Its recombinant form is critical for elucidating MAPKBP1’s roles in disease mechanisms and developing pathway-specific therapies.
