KHSRP Antibody

About the Target

P75 is a target of interest in many antibody-based workflows. KHSRP (KH-type splicing regulatory protein), also known as FUBP2 or FUSE-binding protein 2, is a multifunctional nucleic acid-binding protein characterized by four KH (K homology) domains and an RS domain, which together enable high specificity for single-stranded RNA and DNA targets. The KH domains, particularly KH3 and KH4, function as independent modules that recognize different regions of AU-rich RNA elements, providing structural flexibility for binding diverse mRNA targets and facilitating mRNA decay. Depending on the literature source, P75 may also be discussed as KHSRP and FUBP2.

Reported cellular context includes cytoplasm and nucleus, which can matter when signal is compared across treatments or changing cell states. Following P75 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

P75 is commonly interpreted in the context of cancer and dna damage / repair research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans 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 cytoplasm and nucleus across matched conditions
• changes associated with proliferative state, oncogenic signaling, or treatment response
• stress-induced changes after checkpoint activation or genotoxic challenge
• 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 P75. 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 P75 reflect biology rather than handling. When interpreting P75, 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 P75 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.
