Alpha II Spectrin antibody recognizes Spectrin alpha chain, non-erythrocytic 1, also referred to as SPTAN1 antibody and Alpha Fodrin antibody, a large cytoskeletal scaffolding protein belonging to the spectrin family. Encoded by the SPTAN1 gene, this protein is widely expressed in non-erythroid tissues and localizes primarily to the cytoplasm and inner surface of the plasma membrane, where it forms heterodimers with beta spectrin to establish a supportive submembranous network. Alpha II Spectrin Antibody SPTAN1/3352 targets this structural protein for research applications investigating cytoskeletal organization and membrane stability.
Spectrin alpha chain, non-erythrocytic 1 plays a critical role in maintaining cell shape, mechanical integrity, and membrane protein positioning. By assembling into tetrameric spectrin complexes, SPTAN1 links transmembrane proteins to the actin cytoskeleton, thereby regulating membrane architecture and intracellular signaling. The protein is particularly abundant in neurons, where it contributes to axonal stability, synaptic organization, and dendritic structure. It is also present in epithelial and other somatic cell types, reflecting its essential role in non-erythroid cellular architecture.
Alpha-II spectrin participates in multiple signaling pathways through interactions with ion channels, adhesion molecules, and regulatory proteins. During apoptosis and neuronal injury, SPTAN1 is proteolytically cleaved by calpains and caspases, generating characteristic spectrin breakdown products that are widely studied as markers of cytoskeletal disruption. These cleavage events are relevant in neurodegenerative disease research, traumatic brain injury studies, and models of cellular stress.
The SPTAN1 gene is located on chromosome 9q33.2 and encodes a multidomain protein containing repetitive spectrin motifs that mediate dimerization and actin binding. Mutations in SPTAN1 have been associated with neurodevelopmental disorders, including epileptic encephalopathy and other neurological syndromes, underscoring its importance in neuronal maturation and stability. Altered spectrin organization has also been linked to changes in cell motility and tumor progression.
Clone SPTAN1/3352 is a monoclonal antibody that recognizes Alpha-II spectrin and supports detection of SPTAN1 expression in research models. By targeting this cytoskeletal scaffold, Alpha II Spectrin antibody facilitates studies of membrane organization, neuronal integrity, apoptosis-related proteolysis, and spectrin-dependent signaling pathways.
Optimal dilution of the Alpha II Spectrin antibody should be determined by the researcher.
A recombinant human partial protein (amino acids 2351-2475) was used as the immunogen for this SPTAN1 antibody.
Store the Alpha II Spectrin antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
