p130 Cas Antibody

About the Target

p130Cas (also known as BCAR1) is a multidomain scaffold protein and Src substrate that plays a central role in integrin-mediated signaling at focal adhesions (FAs), where it regulates cell adhesion, motility, proliferation, survival, and tumor progression. It is ubiquitously expressed in mammalian cells, especially those involved in adhesion and migration, and is upregulated and hyperphosphorylated in various cancers, including breast cancer, where it contributes to tamoxifen resistance. Depending on the literature source, BCAR1 may also be discussed as p130 Cas.

Reported cellular context includes cell junction, cell projection, and cytoplasm, which can matter when signal is compared across treatments or changing cell states. Following BCAR1 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

BCAR1 is commonly interpreted in the context of cancer 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 projection, and cytoplasm, 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 projection, and cytoplasm across matched conditions
• changes associated with proliferative state, oncogenic signaling, or treatment response
• signal-dependent shifts after ligand, inhibitor, or growth-factor perturbation
• co-patterning with orthogonal markers and control conditions that clarify pathway state

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for BCAR1. 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 BCAR1 reflect biology rather than handling. When interpreting BCAR1, 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 BCAR1 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.
