Homer1 Antibody

About the Target

Homer1 is a synaptic scaffolding protein encoded by the HOMER1 gene, essential for glutamatergic synapse organization and plasticity. Structurally, it contains an N-terminal EVH1 domain, which interacts with PPXXF motifs in proteins like mGluRs, IP3 receptors, and Shank proteins, and longer isoforms (Homer1b/c) possess a C-terminal coiled-coil domain that mediates multimerization, forming a matrix-like structure in dendritic spines.

Reported cellular context includes cell projection, cytoplasm, and synapse, which can matter when signal is compared across treatments or changing cell states. Following HOMER1 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

HOMER1 is commonly interpreted in the context of neuroscience and cell signaling research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell projection, cytoplasm, and synapse, 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 projection, cytoplasm, and synapse across matched conditions
• compartment-specific patterns relevant to neuronal polarity, transport, or synaptic context
• signal-dependent shifts after ligand, inhibitor, or growth-factor perturbation
• 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 HOMER1. 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 HOMER1 reflect biology rather than handling. When interpreting HOMER1, 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 HOMER1 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.
