SUV39H1 Antibody

About the Target

The human histone methyltransferase SUV39H1 corresponds to the prominent Drosophila PEV modifier Su(var)3-9 and comprises 412 amino acid residues. It amalgamates two highly conserved domains among "chromatin regulators": the chromo and SET domains. The chromo domain, spanning 60 amino acids, embodies an ancient histone-like structure directing localization to heterochromatin. Depending on the literature source, SUV39H1 may also be discussed as KMT1A.

Reported cellular context includes cell membrane, centromere, chromosome, and cytoplasmic vesicle, which can matter when signal is compared across treatments or changing cell states. Following SUV39H1 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

SUV39H1 is commonly interpreted in the context of epigenetics research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell membrane, centromere, and chromosome, 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 membrane, centromere, and chromosome across matched conditions
• links between target behavior and transcriptional or chromatin-state changes
• co-patterning with orthogonal markers and control conditions that clarify pathway state
• time-matched comparisons so changes reflect biology rather than handling or sampling drift

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for SUV39H1. 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 SUV39H1 reflect biology rather than handling. When interpreting SUV39H1, 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 SUV39H1 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.
