Preparation and Storage

Background: beta-III Spectrin

Spectrin beta-III (SPTBN2) belongs to spectrins family of proteins which are essential to mechanical support/structural membrane integrity maintenance in erythrocytes, stabilizing cell-cell contacts, and localizing ion channels as well as cell adhesion molecules within specific subdomains of plasma membranes. Vertebrate spectrins have two alpha-subunits (alpha-I/alpha-II), four beta-subunits (beta-I-beta-IV) and a beta-H subunit creating diversity and specialization of function. Spectrin beta 3 is primarily expressed in nervous tissues with highest expression levels in the cerebellum, where it is found in Purkinje cell soma and dendrites. Spectrin beta-III interacts with EAAT4, the glutamate transporter predominately expressed in Purkinje cells, and stabilizes it at the plasma membrane leading to glutamate clearance from the synaptic cleft, and resulting in both modulation of glutamatergic neurotransmission as well as prevention of glutamate-mediated neurotoxicity.
