TPX2 Antibody

About the Target

TPX2 (Targeting Protein for Xklp2) is a microtubule-associated protein encoded by the TPX2 gene and plays a key role in mitotic spindle assembly during cell division. Structurally, TPX2 is an elongated monomeric protein with distinct functional regions, including an N-terminus that interacts with Aurora A kinase to activate it and target it to the spindle, and a C-terminus that interacts with mitotic kinesins like Kif11/Eg5 and Kif15/Xklp2.

Reported cellular context includes cytoplasm, cytoskeleton, microtubule, and nucleus, which can matter when signal is compared across treatments or changing cell states. Following TPX2 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

TPX2 is commonly interpreted in the context of cancer and cell cycle research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cytoplasm, cytoskeleton, and microtubule, 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 cytoplasm, cytoskeleton, and microtubule across matched conditions
• changes associated with proliferative state, oncogenic signaling, or treatment response
• cell-cycle linked differences in abundance, timing, or compartmental enrichment
• 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 TPX2. 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 TPX2 reflect biology rather than handling. When interpreting TPX2, 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 TPX2 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.
