The CTNND1 (Phospho-Tyr257) antibody is designed to detect delta-catenin (CTNND1) when phosphorylated at tyrosine residue 257. CTNND1. a member of the catenin family, plays a critical role in cell-cell adhesion, synaptic function, and cellular signaling by interacting with cadherins, cytoskeletal proteins, and transcriptional regulators. Phosphorylation at Tyr257 modulates CTNND1's activity, influencing its ability to regulate cell motility, membrane dynamics, and Wnt signaling pathways. This post-translational modification is often associated with tyrosine kinase signaling cascades, such as those involving Src family kinases, which are implicated in cancer progression and neurological disorders.
The antibody is widely used in research to study CTNND1's phosphorylation-dependent roles in physiological and pathological contexts. For example, aberrant CTNND1 phosphorylation has been linked to tumor invasiveness, metastasis, and neurodegenerative diseases like Alzheimer's. By specifically recognizing the phosphorylated Tyr257 epitope, this antibody enables the detection of activated CTNND1 in techniques such as Western blotting, immunofluorescence, and immunohistochemistry. Its applications extend to exploring mechanisms of cell adhesion disruption, epithelial-mesenchymal transition (EMT), and synaptic plasticity, providing insights into therapeutic targeting of CTNND1-related pathways in cancer and neurological conditions.
