Key elements and design rationale
- Target: SLC7A3 (Cationic amino acid transporter 3). Alternative names: Cationic amino acid transporter 3;CAT-3;CAT3;Cationic amino acid transporter y+;Solute carrier family 7 member 3;SLC7A3;ATRC3, CAT3;
- Antibody format: Polyclonal; Rabbit IgG
- Species context: Host: Rabbit, Reactivity: Human
- Purification: Immunogen affinity purified.
- Immunogen: A synthetic peptide corresponding to a sequence at the C-terminus of human SLC7A3.
- Molecular weight context: observed 70 kDa, calculated 67169 MW (reported)
- Provided application(s): WB, IHC, Flow, ELISA
These attributes help contextualize how the antibody is commonly selected (host/clonality/isotype/label) and how signals are interpreted across sample types and assay formats.
Biological background
Function: Mediates the uptake of the cationic amino acids arginine, lysine and ornithine in a sodium-independent manner. .
Cellular localization: Cell membrane; Multi-pass membrane protein.
Tissue details: Highly expressed in thymus, uterus and testis. Detected at lower levels in brain, mammary gland, prostate, salivary gland and fetal spleen. In brain, highest expression in thalamus, hippocampus and amygdala. .
Background: Cationic amino acid transporter 3 is a protein that in humans is encoded by the SLC7A3 gene. This gene encodes a member of the solute carrier family 7. The encoded protein is a sodium-independent cationic amino acid transporter. Alternate splicing results in multiple transcripts that encoded the same protein. The International Radiation Hybrid Mapping Consortium mapped the SLC7A3 gene to the X chromosome.
Cross reactivity: No cross-reactivity with other proteins.
Research relevance and current trends
- Quantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.
- Isoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.
- Context-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.
Common research applications
- Western blot (WB): compare relative target abundance and apparent size shifts (e.g., isoforms/PTMs) across conditions.
- Immunohistochemistry (IHC): assess distribution across tissue compartments and compare staining patterns between groups.
- Flow cytometry: quantify target-positive populations and compare shifts after stimulation or differentiation.
Across these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.
Notes for experimental interpretation
- Apparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.
- Species reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.
- Control concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO/KD, peptide competition, or independent assays) to support interpretation.
For antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.
