Overview
Recombinant Human Reduced folate transporter (SLC19A1), partial is a recombinant protein reagent derived from Homo sapiens (Human) and produced in E.coli. It is commonly used to support Others research by enabling binding assays, assay development and protein–protein interaction studies in controlled in vitro settings.
Key elements and design rationale
- Expressed region: 420-591aa. Region selection can focus on functional domains, improve solubility, or isolate interaction surfaces for targeted studies.
- Expression system: E.coli. Expression host can influence folding and the presence/absence of post-translational modifications.
- Tag / fusion: N-terminal 10xHis-tagged and C-terminal Myc-tagged. Tags can support purification and detection; evaluate potential tag effects when studying sensitive interactions.
- Molecular weight (reported): 25.5 kDa. Apparent size may vary with tags, processing, and gel conditions.
When comparing results across batches or platforms, interpret signals in the context of construct design (region, tags) and expression host, especially for modification-dependent interactions.
Biological background
The gene commonly associated with this target is SLC19A1. SLC19A1 refers to a protein target that is studied across multiple biological contexts; annotations and nomenclature can vary by species and isoform. This product corresponds to the Homo sapiens (Human) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt/NCBI) and the recent literature for the specific organism and isoform.
Research relevance and current trends
- Using recombinant proteins to enable quantitative binding measurements and reagent benchmarking.
- Studying domain- and isoform-specific effects in pathway models and interaction networks.
- Developing robust, reproducible assays that connect molecular readouts to cellular phenotypes.
Relevance: Antiporter that mediates the import of reduced folates or a subset of cyclic dinucleotides, driven by the export of organic anions. Mechanistically, acts as a secondary active transporter, which exports intracellular organic anions down their concentration gradients to facilitate the uptake of its substrates. Has high affinity for N5-methyltetrahydrofolate, the predominant circulating form of folate. Also able to mediate the import of antifolate drug methotrexate. Also acts as an importer of immunoreactive cyclic dinucleotides, such as cyclic GMP-AMP (2'-3'-cGAMP), an immune messenger produced in response to DNA virus in the cytosol, and its linkage isomer 3'-3'-cGAMP, thus playing a role in triggering larger immune responses. 5-amino-4-imidazolecarboxamide riboside (AICAR), when phosphorylated to AICAR monophosphate, can serve as an organic anion for antiporter activity.
Common research applications
- Assay and standard development for immunoassays or binding-based detection methods.
- Protein–protein interaction studies (e.g., receptor–ligand or complex assembly) using purified components.
- Structure–function analysis, including domain mapping or evaluation of sequence variants.
In quantitative assay development, changes in binding or activity readouts are typically interpreted relative to appropriate negative/positive controls and, where possible, orthogonal assay formats that support the same conclusion.
Notes for experimental interpretation
- Recombinant constructs may represent a defined region (domain) rather than the full-length protein; interpret results in the context of the expressed region.
- Tag or fusion elements can aid purification and detection but may influence binding surfaces or oligomerization; consider tag controls when relevant.
- Species and isoform differences can affect interaction partners and post-translational modifications; align experimental controls to the intended biological context.
- E. coli expression can limit eukaryotic post-translational modifications; for modification-dependent biology, interpret results accordingly.
