Spectrin beta III Antibody / SPTBN2

Spectrin is an actin binding protein that is a major component of the plasma membrane skeleton. Spectrins function as membrane organizers and stabilizers by forming dimers, tetramers and higher polymers. Spectrin alpha and spectrin beta are present in erythrocytes, whereas spectrin alpha II (fodrin a) and spectrin beta I (fodrin b) are present in other somatic cells. SPTBN2/Spectrin beta III is highly homologous to both spectrin beta I and spectrin beta II. SPTBN2 is highly expressed in brain, kidney, pancreas and liver, and at lower levels in lung and placenta.
