GFPT2 Antibody

About the Target

GFPT2(Glutamine-fructose-6-phosphate transaminase 2) is a key isoenzyme and the rate-limiting enzyme of the hexosamine biosynthetic pathway (HBP), which diverts glucose metabolism to generate UDP-GlcNAc for protein O-GlcNAcylation. GFPT2 shares homology with GFPT1 and contains conserved binding domains for fructose-6-phosphate and glutamine. Unlike GFPT1, GFPT2 is activated by phosphorylation at serine 202 by PKA. Depending on the literature source, GFPT2 may also be discussed as Glutamine-fructose-6-phosphate aminotransferase [isomerizing] 2 and D-fructose-6-phosphate amidotransferase 2.

Reported cellular context includes cytosol, which can matter when signal is compared across treatments or changing cell states. Following GFPT2 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

GFPT2 is commonly interpreted in the context of cancer and metabolism research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cytosol, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• signal enrichment within cytosol relative to the broader cellular background
• changes associated with proliferative state, oncogenic signaling, or treatment response
• responses linked to nutrient status, mitochondrial state, or metabolic rewiring
• 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 GFPT2. 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 GFPT2 reflect biology rather than handling. When interpreting GFPT2, 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 GFPT2 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.
