SPTBN1

Template:Short description An Error has occurred retrieving Wikidata item for infobox Spectrin beta chain, brain 1 is a protein that in humans is encoded by the SPTBN1 gene.

Function

Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma 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. The encoded protein contains an N-terminal actin-binding domain, and 17 spectrin repeats that are involved in dimer formation. Multiple transcript variants encoding different isoforms have been found for this gene.

Interactions

SPTBN1 has been shown to interact with Merlin.
