Description

MAPK7, also known as ERK5 or BMK1, represents a distinctive member of the mitogen-activated protein kinase family that plays essential roles in neuronal survival, differentiation, and synaptic plasticity. Unlike other ERK family members, MAPK7 possesses a uniquely extended C-terminal domain that enables transcriptional activation, making it a critical node linking extracellular signals to gene expression programs in both developing and mature nervous systems.

This recombinant monoclonal antibody, generated from clone 19F12, offers the reproducibility and sequence-defined consistency that demanding experimental workflows require. Because recombinant production eliminates the batch variability inherent in traditional hybridoma methods, researchers can confidently compare results across extended studies and between laboratories.

Validation testing demonstrates robust performance across multiple applications and species. In western blot analysis, the antibody detects MAPK7 in human cell lines including HeLa, MCF-7, Jurkat, HEK293, COLO-205, and SH-SY5Y, as well as mouse and rat brain tissue lysates. The observed band at 115 kDa runs higher than the predicted 88 kDa molecular weight, consistent with post-translational modifications including phosphorylation events that regulate MAPK7 activity. Immunohistochemistry validation in human stomach and liver cancer tissues confirms reliable detection in formalin-fixed paraffin-embedded samples, while immunofluorescence staining in HeLa cells reveals subcellular localization patterns suitable for imaging studies.

Cross-species reactivity with human, mouse, and rat samples, combined with flexibility across ELISA, western blot, immunohistochemistry, and immunofluorescence platforms, makes this antibody particularly valuable for neuroscience researchers investigating MAPK7 signaling in disease models, developmental studies, or translational research contexts.

Target Background

Function

Plays a role in various cellular processes such as proliferation, differentiation and cell survival. The upstream activator of MAPK7 is the MAPK kinase MAP2K5. Upon activation, it translocates to the nucleus and phosphorylates various downstream targets including MEF2C. EGF activates MAPK7 through a Ras-independent and MAP2K5-dependent pathway. May have a role in muscle cell differentiation. May be important for endothelial function and maintenance of blood vessel integrity. MAP2K5 and MAPK7 interact specifically with one another and not with MEK1/ERK1 or MEK2/ERK2 pathways. Phosphorylates SGK1 at Ser-78 and this is required for growth factor-induced cell cycle progression. Involved in the regulation of p53/TP53 by disrupting the PML-MDM2 interaction.
