Biological background
p120 Catenin was first identified as a substrate of Src family kinases and is now recognized as a central adaptor in adherens junctions, where it binds directly to the juxtamembrane domain of classical cadherins. Research using Phospho-p120 Catenin (Tyr228) antibody has shown that phosphorylation at Tyr228 modifies its cadherin-binding affinity, affecting junction stability and turnover. This phosphorylation also alters signaling through Rho family GTPases, impacting actin cytoskeleton dynamics and cell motility.
Studies with Phospho-p120 Catenin (Tyr228) antibody have revealed that the Tyr228 site is phosphorylated in response to growth factor stimulation, mechanical stress, and oncogenic signaling. Src and receptor tyrosine kinases mediate this modification, linking extracellular cues to junction remodeling. By regulating cell-cell adhesion, phosphorylation at Tyr228 influences epithelial-mesenchymal transition, tissue morphogenesis, and tumor invasion.
In cancer biology, aberrant phosphorylation of p120 Catenin contributes to disease progression. Research using Phospho-p120 Catenin (Tyr228) antibody has shown that elevated phosphorylation disrupts cadherin-mediated adhesion, enabling tumor cells to detach and migrate. At the same time, phosphorylation-dependent regulation of Rho family proteins promotes cytoskeletal reorganization and invasiveness. These findings highlight p120 Catenin Tyr228 phosphorylation as a potential biomarker of metastasis and therapeutic target.
Beyond cancer, p120 Catenin phosphorylation influences cardiovascular and developmental processes. Studies with Phospho-p120 Catenin (Tyr228) antibody have revealed roles in vascular integrity, cardiac morphogenesis, and neural crest development. Dysregulation of this pathway may contribute to congenital defects and vascular diseases. Because p120 Catenin integrates adhesive and signaling functions, its phosphorylation status provides insight into multiple physiological and pathological processes.
Phospho-p120 Catenin (Tyr228) antibody is widely used in western blotting, immunohistochemistry, and immunofluorescence. Western blotting distinguishes phosphorylated from non-phosphorylated forms, immunohistochemistry identifies activated signaling regions in tissues, and immunofluorescence demonstrates subcellular distribution of phosphorylated protein at junctions and in the cytoplasm. These applications make the antibody valuable in adhesion and signaling research.

Research relevance and current trends
- Connecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).
- Quantifying post-translational regulation (including phosphorylation) alongside total protein levels.
- Comparing results across species and model systems with matched controls.
Common research applications
- Western blotting: compare relative abundance and activation-state changes across conditions.
- Immunohistochemistry: map target signal in tissue context and compare regions/phenotypes.
Interpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.
Notes for experimental interpretation
- Signal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.
- Phospho-site readouts are condition-dependent and are often compared to total target levels when available.
- Species differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.
Antibody notes: Monoclonal antibodies provide a defined epitope recognition profile that can support consistent comparisons across experiments.
