DUSP3 (Dual Specificity Phosphatase 3), also known as Vaccinia H1-related phosphatase (VHR), is a member of the dual-specificity phosphatase family. It regulates mitogen-activated protein kinase (MAPK) signaling pathways by dephosphorylating critical tyrosine and threonine residues on ERK, JNK, and p38 kinases. DUSP3 plays a role in cellular processes such as proliferation, differentiation, and apoptosis, with implications in cancer, immune responses, and angiogenesis. Studies suggest it may act as both tumor suppressor and promoter depending on context, highlighting its complex regulatory functions.
DUSP3 antibodies are essential tools for detecting and quantifying DUSP3 protein expression in research. They are widely used in techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF) to study its localization, expression patterns, and interactions in various tissues and disease models. High-quality DUSP3 antibodies exhibit specificity for distinct isoforms and phosphorylation states, enabling precise investigation of its activity. Recent research has linked DUSP3 dysregulation to diseases such as breast cancer, leukemia, and inflammatory disorders, driving demand for reliable antibodies to explore its therapeutic potential. Validation using knockout controls or siRNA is critical to ensure antibody specificity in experimental settings.
