== Function ==
[[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.

Mutations in SPT α are found in patients with hereditary elliptocytosis<ref>PMID:2346784</ref>. SPT β deficiency is found in hereditary spherocytosis<ref>PMID:9714702</ref>.
