MST4 Antibody

About the Target

The mammalian STE20-like protein kinase 4 (MST4), also known as STK26, is a serine/threonine kinase belonging to the germinal center kinase (GCK) subfamily III, alongside MST3 and STK25. MST4 is predominantly expressed in human thymus, placenta, lymphocytes, and leukocytes, where it regulates essential cellular processes including mitosis, polarity, migration, apoptosis, and differentiation.

Reported cellular context includes cytoplasm and golgi apparatus, which can matter when signal is compared across treatments or changing cell states. Following MST4 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

MST4 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 cytoplasm and golgi apparatus, 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 and golgi apparatus 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 MST4. 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 MST4 reflect biology rather than handling. When interpreting MST4, 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 MST4 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.
