Spectrin-based membrane skeleton supports ciliogenesis.
Cilia are remarkable cellular devices that power cell motility and transduce extracellular signals. To assemble a cilium, a cylindrical array of 9 doublet microtubules push out an extension of the plasma membrane.

Abstract Spectrins are large, rod-like, multifunctional molecules that participate in maintaining cell structure, signal transmission, and DNA repair. Because little is known about the role of spectrins in normal hematopoiesis and leukemogenesis, we immunohistochemically stained bone marrow biopsy specimens from 81 patients for αI, αII ...

Spectrin functions upstream of ankyrin in a spectrin cytoskeleton assembly pathway [PDF]
Prevailing models place spectrin downstream of ankyrin in a pathway of assembly and function in polarized cells. We used a transgene rescue strategy in Drosophila melanogaster to test contributions of four specific functional sites in β spectrin to its assembly and function.

Calmodulin binding to human spectrin [PDF]
Calmodulin is shown to interact with human spectrin dimer. The binding was highly calcium‐dependent and observed in two different kinds of experiments. Firstly, affinity chromatography of calmodulin on a Sepharose 4B column with immobilized spectrin, and secondly, partition in aqueous two‐phase polymer systems.

αI-spectrin represents evolutionary optimization of spectrin for red blood cell deformability [PDF]
Spectrin tetramers of the membranes of enucleated mammalian erythrocytes play a critical role in red blood cell survival in circulation. One of the spectrins, αI, emerged in mammals with enucleated red cells following duplication of the ancestral α ...

β-III-spectrin N-terminus is required for high-affinity actin binding and SCA5 neurotoxicity
Recent structural studies of β-III-spectrin and related cytoskeletal proteins revealed N-terminal sequences that directly bind actin. These sequences are variable in structure, and immediately precede a conserved actin-binding domain composed of tandem ...

Long noncoding RNA regulation of spermatogenesis via the spectrin cytoskeleton in Drosophila
The spectrin cytoskeleton has been shown to be critical in diverse processes such as axon development and degeneration, myoblast fusion, and spermatogenesis.

Mena/VASP and αII-Spectrin complexes regulate cytoplasmic actin networks in cardiomyocytes and protect from conduction abnormalities and dilated cardiomyopathy [PDF]
BACKGROUND: In the heart, cytoplasmic actin networks are thought to have important roles in mechanical support, myofibrillogenesis, and ion channel function.
