[[Spectrin]] forms scaffolding in plasma membranes and cytoskeletal structure. It interacts with actin at either end of its tetramer<ref>PMID:17060500</ref>. The SPT dimer is formed by association of α1 and β1 monomers. In invertebrates there are SPT α, β and βH. In vertebrates there are SPT α1 (SPTA1), α2 (SPTA2) and β1 (SPTB1) to β5. SPT contains an SRC Homology 3 domain (SH3), a Pleckstrin Homology (PH) domain and a Calponin Homology (CH) domain. | [[Spectrin]] forms scaffolding in plasma membranes and cytoskeletal structure.
