背景信息

The HER4 (Phospho-Tyr1284) antibody is a specialized tool used to detect the phosphorylated form of HER4 (ErbB4) at tyrosine residue 1284. HER4. a member of the epidermal growth factor receptor (EGFR) family, plays a critical role in cell signaling pathways regulating proliferation, differentiation, and survival. Upon ligand binding (e.g., neuregulins), HER4 undergoes dimerization and autophosphorylation at specific tyrosine residues, including Y1284. which serves as a docking site for adaptor proteins like Shc and PI3K. This phosphorylation event is essential for activating downstream signaling cascades, such as MAPK and Akt pathways, influencing cellular responses. The HER4 (Phospho-Tyr1284) antibody specifically recognizes this post-translational modification, enabling researchers to study HER4 activation status in various contexts, such as cancer, development, and tissue homeostasis. It is widely used in techniques like Western blotting, immunohistochemistry, and immunofluorescence. Dysregulated HER4 signaling has been implicated in breast cancer, ovarian cancer, and neurodegenerative diseases, making this antibody valuable for both mechanistic research and biomarker analysis. Validation of its specificity through knockout controls or phosphorylation-blocking assays is recommended to ensure accurate detection in experimental models.
