Phospho-Zyxin (Ser142/143) Antibody

About the Target

Phospho-zyxin (Ser 142/143) is the phosphorylated form of zyxin, a mechanosensitive LIM domain-containing focal adhesion protein critical for actin cytoskeleton organization and cell signaling. Expressed in various cell types, particularly endothelial and muscle cells, its phosphorylation at serine residues 142 and 143-mediated by kinases like PKA-enhances its interaction with actin filaments and focal adhesion components. Depending on the literature source, ZYXIN may also be discussed as Phospho-Zyxin (Ser142/143).

Reported cellular context includes cell junction, cytoplasm, cytoskeleton, and nucleus, which can matter when signal is compared across treatments or changing cell states. Following ZYXIN across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

ZYXIN is commonly interpreted in the context of cardiovascular and cell signaling research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell junction, cytoplasm, and cytoskeleton, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• apparent redistribution between cell junction, cytoplasm, and cytoskeleton across matched conditions
• changes linked to vascular, contractile, or hemodynamic cell-state cues
• signal-dependent shifts after ligand, inhibitor, or growth-factor perturbation
• differences between total target abundance and site-specific regulation when modified forms are compared

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for ZYXIN. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.

Standardize sampling time, control choice, and downstream analysis thresholds so apparent differences in ZYXIN reflect biology rather than handling. When interpreting ZYXIN, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.

For multi-run studies, a shared reference condition can keep ZYXIN trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.
