Spectrin beta non-erythrocytic 4 also known as SPTBN4 is a protein that in humans is encoded by the SPTBN4 gene.Spectrin is an actin crosslinking and molecular scaffold protein that links the cell membrane to the actin cytoskeleton and functions in the determination of cell shape arrangement of transmembrane proteins and organization of organelles. It is composed of two antiparallel dimers of alpha- and beta- subunits. This gene is one member of a family of beta-spectrin genes.
