Phospho-FoxO3a (Ser413) Antibody

About the Target

FOXO3 is a target of interest in many antibody-based workflows. The forkhead box O (FoxO) transcription factors are pivotal players in numerous physiological and pathological processes, spanning apoptosis, cell cycle regulation, stress response, glucose metabolism, cellular differentiation, development, and tumor suppression. The potent functions of FoxOs are intricately regulated through various mechanisms, encompassing posttranslational modifications such as phosphorylation, acetylation, methylation, and ubiquitination, subcellular localization, and direct protein-protein interactions. Depending on the literature source, FOXO3 may also be discussed as Phospho-FoxO3a (Ser413).

Reported cellular context includes cytoplasm, membrane, mitochondrion, and mitochondrion outer membrane, which can matter when signal is compared across treatments or changing cell states. Following FOXO3 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

FOXO3 is commonly interpreted in the context of metabolism and developmental biology research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cytoplasm, membrane, and mitochondrion, 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, membrane, and mitochondrion across matched conditions
• responses linked to nutrient status, mitochondrial state, or metabolic rewiring
• stage-dependent patterns during differentiation, morphogenesis, or lineage commitment
• differences between total target abundance and site-specific regulation when modified forms are compared

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for FOXO3. 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 FOXO3 reflect biology rather than handling. When interpreting FOXO3, 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 FOXO3 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.
