Nectin-4 Antibody

About the Target

PRR4 is a target of interest in many antibody-based workflows. Nectin4 is a type I transmembrane glycoprotein belonging to the immunoglobulin superfamily (IgSF), structurally composed of three extracellular Ig-like domains (one V-type and two C2-type), a single transmembrane domain, and a short cytoplasmic tail containing a PDZ-binding motif that interacts with the actin-binding adaptor protein Afadin. While human Nectin4 expression is largely restricted to the placenta, it shows broader tissue distribution in mice, including brain, lung, testis, and developing embryos. Depending on the literature source, PRR4 may also be discussed as Nectin-4 and LNIR.

Reported cellular context includes cell junction, cell membrane, membrane, and secreted, which can matter when signal is compared across treatments or changing cell states. Following PRR4 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

PRR4 is commonly interpreted in the context of developmental biology, infectious disease, 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, cell membrane, and membrane, 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, cell membrane, and membrane across matched conditions
• stage-dependent patterns during differentiation, morphogenesis, or lineage commitment
• host-response changes during infection or pathogen-associated stimulation
• signal-dependent shifts after ligand, inhibitor, or growth-factor perturbation

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for PRR4. 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 PRR4 reflect biology rather than handling. When interpreting PRR4, 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 PRR4 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.
