Biological background
Protein function (datasheet): SPTA1: Spectrin is the major constituent of the cytoskeletalnetwork underlying the erythrocyte plasma membrane. It associateswith band 4.1 and actin to form the cytoskeletal superstructure ofthe erythrocyte plasma membrane.|SPTB: Spectrin is the major constituent of the cytoskeletalnetwork underlying the erythrocyte plasma membrane. It associateswith band 4.1 and actin to form the cytoskeletal superstructure ofthe erythrocyte plasma membrane.
Scientific background (datasheet): Spectrin, the predominant component of the membrane skeleton of the red cell, is essential in determining the properties of the membrane including its shape and deformability. It consists of 2 nonidentical subunits, alpha and beta. Spectrin is present in the red cell membrane in a tetrameric or possibly higher polymeric form through head-to-head self-association of heterodimers that are linked by actin polymers and protein 4.1 to form a 2-dimensional network. Non-erythroid spectrin gene is mapped to human chromosome 2. Spectrin mutations cause spinocerebellar ataxia type 5.
Cellular localization (datasheet): SPTA1: Cytoplasm, cytoskeleton. Cytoplasm, cellcortex.|Spta1: Cytoplasm, cytoskeleton. Cytoplasm, cellcortex.|SPTB: Cytoplasm, cytoskeleton. Cytoplasm, cellcortex.|Sptb: Cytoplasm, cytoskeleton. Cytoplasm, cellcortex.
Sequence similarities (datasheet): Belongs to the spectrin family.
Research relevance and current trends
- Commonly studied in contexts related to Actin, etc.,Cytoskeleton,Cytoskeleton/ECM,Microfilaments,Plasma Membrane,Signal Transduction,Subcellular Markers,Tags & Cell Markers.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a monoclonal antibody, this reagent is expected to recognize a defined epitope, which can support consistency across lots when epitope accessibility is preserved.
