Biological background
Functionally, RASAL3 antibody identifies a 944-amino-acid cytoplasmic protein containing C2 and RasGAP domains responsible for lipid membrane binding and GTPase activation. RASAL3 inhibits Ras-dependent pathways, including ERK/MAPK signaling, limiting excessive immune cell activation and promoting homeostasis. It acts downstream of receptor stimulation to fine-tune immune responses.
The RASAL3 gene is located on chromosome 19q13.3 and is highly expressed in natural killer cells, T cells, and macrophages. It serves as a negative feedback regulator of immune activation by controlling Ras signaling intensity following antigen or cytokine stimulation. In NK cells, RASAL3 influences cytotoxic granule release and antiviral responses.
Pathologically, dysregulation of RASAL3 contributes to immune dysfunction and inflammation. Loss of function enhances Ras activity, promoting lymphoproliferative and autoimmune phenotypes. In cancer, RASAL3 downregulation may facilitate tumor immune evasion by disturbing immune regulation. Research using RASAL3 antibody supports investigations into Ras pathway modulation, immune signaling, and oncogenic Ras control.
RASAL3 antibody is validated for western blotting, immunohistochemistry, and flow cytometry to detect RasGAP proteins and Ras activity regulators.
Structurally, Ras GTPase-activating-like protein 3 contains an N-terminal C2 lipid-binding domain and a C-terminal catalytic GAP domain. This architecture enables membrane association and inactivation of Ras. This antibody facilitates research on RASAL3's inhibitory role in signal transduction and immune modulation.
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.
- Immunohistochemistry: map target signal in tissue context and compare regions/phenotypes.
- Flow cytometry: quantify target-positive populations and signal shifts at single-cell resolution.
- 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.
