Phospho-TFEB (Ser211) Antibody

About the Target

Phospho-TFEB (Ser211) refers to the phosphorylated form of transcription factor EB (TFEB) at serine residue 211, a critical regulatory site within its structure. TFEB is a basic helix-loop-helix-leucine zipper (bHLH-Zip) transcription factor of the MiT/TFE family that controls genes involved in autophagy, lysosomal biogenesis, and cellular clearance. Depending on the literature source, TFEB may also be discussed as Phospho-TFEB (Ser211) and Transcription factor EB.

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

Research Context

TFEB is commonly interpreted in the context of cell signaling research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cytoplasm, lysosome, and membrane, 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, lysosome, and membrane across matched conditions
• signal-dependent shifts after ligand, inhibitor, or growth-factor perturbation
• differences between total target abundance and site-specific regulation when modified forms are compared
• 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 TFEB. 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 TFEB reflect biology rather than handling. When interpreting TFEB, 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 TFEB 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.
