Biological background
RFX4 is encoded by the RFX4 gene located on human chromosome 12q23.1. Alternative splicing of this gene produces several isoforms, including RFX4_v1, RFX4_v2, and RFX4_v3, each differing in transcriptional activity and tissue expression. The protein contains a conserved DNA-binding domain characteristic of RFX family members, as well as a dimerization domain that allows heterodimer formation with other RFX proteins such as RFX2 or RFX3. These interactions contribute to complex transcriptional control of cilia-related genes, making RFX4 a central node in the regulation of motile and primary cilia biogenesis.
The RFX4 antibody has been instrumental in studies linking gene expression patterns to developmental brain disorders. Loss-of-function mutations or altered RFX4 expression have been associated with congenital hydrocephalus, holoprosencephaly, and various neurodevelopmental syndromes. Mouse models deficient in Rfx4 show severe forebrain malformations and altered neuronal differentiation, demonstrating its crucial role in brain patterning. Beyond the CNS, RFX4 contributes to the regulation of genes expressed in reproductive and endocrine tissues, including those controlling gonadotropin-releasing hormone production and pituitary signaling. Researchers use this antibody for western blot, immunohistochemistry, and immunofluorescence to monitor its expression during neurogenesis and in cultured cells undergoing differentiation.
In experimental systems, RFX4 localizes mainly to the nucleus, where it binds target promoters and interacts with co-regulatory proteins such as CREB-binding protein (CBP) and EP300. Studies using chromatin immunoprecipitation and transcriptome analyses have revealed that RFX4 controls transcriptional programs tied to ciliary trafficking, cell polarity, and synaptic development.
Research relevance and current trends
- Connecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).
- Considering isoforms and post-translational regulation when interpreting protein-level changes.
- Comparing results across species and model systems with matched controls.
Common research applications
- Western blotting: compare relative abundance and activation-state changes across conditions.
- ELISA: support antibody-based quantification in assay formats where applicable.
Interpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.
Notes for experimental interpretation
- Signal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.
- Species differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.
Antibody notes: Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.
