General description
Spectrin beta (UniProt: G1SN11) is encoded by the SPTBN1 gene in rabbit. Spectrins belong to the superfamily of proteins called F-actin cross linking proteins that function as scaffolding proteins for protein sorting, cell adhesion, and migration. They are principle components of a cell membrane-cytoskeleton and are composed of two alpha and two beta spectrin subunits. They are actin binding proteins that serves as a membrane organizer and stabilizer. Spectrin beta II is a multifunctional protein that contains lipid-binding sites within its two calponin-homology domains (aa 82-186 and 201-306) and a pleckstrin homology domain (aa 2224-2334) and triple helical segments. Spectrin beta II is generally associated with the cytoplasmic surface of the membrane by attachment to ankyrin.
~275 kDa observed; 271.27 kDa calculated. Uncharacterized bands may be observed in some lysate(s).
