Phospho-PTEN (Thr366) Antibody

About the Target

PTEN (Phosphatase and TENsin Homolog deleted on chromosome 10) is a key tumor suppressor protein that regulates multiple cellular processes, including cell proliferation, survival, growth, and motility, primarily by dephosphorylating PIP3 to PIP2, thus inhibiting the PI3K/AKT pathway. Structurally, PTEN contains a phosphatase domain, a C2 lipid membrane-binding domain, and a C-terminal PDZ-binding motif that recognizes target proteins. Depending on the literature source, PTEN may also be discussed as Phospho-PTEN (Thr366).

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

Research Context

PTEN is commonly interpreted in the context of cancer, neuroscience, and metabolism research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell projection, cytoplasm, and nucleus, 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 projection, cytoplasm, and nucleus across matched conditions
• changes associated with proliferative state, oncogenic signaling, or treatment response
• compartment-specific patterns relevant to neuronal polarity, transport, or synaptic context
• responses linked to nutrient status, mitochondrial state, or metabolic rewiring

Variant Considerations

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