Paxillin is a multifunctional adaptor protein that plays a pivotal role in regulating cell adhesion, migration, and signaling by serving as a scaffold for cytoskeletal and signaling molecules. It contains multiple protein-binding domains, including LD motifs and LIM domains, which facilitate interactions with integrins, focal adhesion kinase (FAK), Src family kinases, and other components of focal adhesions. Phosphorylation of paxillin at specific tyrosine residues, such as Tyr88. is a critical regulatory mechanism that modulates its activity during cellular processes. The phosphorylation event at Tyr88 is primarily mediated by FAK or Src kinase in response to integrin engagement or growth factor stimulation. This post-translational modification enhances paxillin's ability to recruit downstream effectors, such as Crk and Rac GTPases, thereby promoting cytoskeletal reorganization and cell motility.
The paxillin (phospho-Tyr88) antibody is a specialized tool designed to detect endogenous levels of paxillin when phosphorylated at tyrosine 88. It is widely used in studies investigating focal adhesion dynamics, cell motility, and cancer metastasis, as Tyr88 phosphorylation is closely associated with tumor invasion and metastatic potential. Researchers employ this antibody in techniques like Western blotting, immunofluorescence, and immunohistochemistry to assess the activation status of paxillin in various cellular contexts. Its specificity for the phosphorylated form allows precise tracking of signaling events linked to extracellular matrix interactions, mechanical stress, or oncogenic transformation. Validated applications often include cancer biology research, particularly in models exploring epithelial-mesenchymal transition (EMT) or drug resistance mechanisms influenced by adhesion-mediated signaling pathways.
