DUSP7 (dual-specificity phosphatase 7), also known as MKPX, is a member of the dual-specificity phosphatase family that regulates mitogen-activated protein kinase (MAPK) signaling pathways. It specifically dephosphorylates and inactivates extracellular signal-regulated kinases (ERK1/2), playing a critical role in controlling cellular responses to growth factors, stress, and cytokines. DUSP7 is expressed in various tissues, with notable activity in immune cells, the brain, and reproductive organs. Its function is tightly linked to cell proliferation, differentiation, and apoptosis, making it a focus in cancer research, particularly in leukemia and solid tumors where MAPK dysregulation is common.
DUSP7 antibodies are essential tools for studying its expression, localization, and interaction partners. These antibodies are typically developed against specific epitopes, such as the N-terminal catalytic domain or C-terminal regions, and validated for applications like Western blotting, immunohistochemistry, and immunofluorescence. High-quality DUSP7 antibodies exhibit specificity confirmed by knockout controls or siRNA knockdowns to avoid cross-reactivity with other DUSP family members (e.g., DUSP1. DUSP6). Research using these antibodies has revealed DUSP7's role in modulating chemoresistance, immune responses, and embryonic development. Recent studies also explore its potential as a therapeutic target, given its regulatory effects on oncogenic signaling pathways. Commercial DUSP7 antibodies are available from multiple suppliers, often accompanied by validation data in peer-reviewed publications.
