αII-spectrin in T cells is involved in the regulation of cell-cell contact leading to immunological synapse formation? [PDF]
T-lymphocyte activation after antigen presentation to the T-Cell Receptor (TCR) is a critical step in the development of proper immune responses to infection and inflammation.

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.

Erythroid and nonerythroid spectrins [PDF]
Abstract Recent developments have contributed important information to understanding the role of spectrins in the RBC membrane skeleton and nonerythroid cells. Many questions can now be framed, informed by structural knowledge of various spectrin subunit types and alternatively spliced variants, that previously could not have been ...

The Physiological Molecular Shape of Spectrin: A Compact Supercoil Resembling a Chinese Finger Trap. [PDF]
The primary, secondary, and tertiary structures of spectrin are reasonably well defined, but the structural basis for the known dramatic molecular shape change, whereby the molecular length can increase three-fold, is not understood.

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.

Hereditary spherocytosis (HS) is a common inherited anemia characterized by the presence of spherocytic red cells. Defects in several membrane protein genes have been involved in the pathogenesis of HS. ß-Spectrin-related HS seems to be common. We report

Spherocytosis-Related L1340P Mutation in Ankyrin Affects Its Interactions with Spectrin
Previously, we reported a new missense mutation in the ANK1 gene that correlated with the hereditary spherocytosis phenotype. This mutation, resulting in L1340P substitution (HGMD CM149731), likely leads to the changes in the conformation of the ankyrin ...

The invasion of the erythrocyte by Plasmodium falciparum depends on the ability of the merozoite to move through the membrane invagination. This ability is probably mediated by actin dependent motors.

The actin binding domain of βI-spectrin regulates the morphological and functional dynamics of dendritic spines. [PDF]
Actin microfilaments regulate the size, shape and mobility of dendritic spines and are in turn regulated by actin binding proteins and small GTPases. The βI isoform of spectrin, a protein that links the actin cytoskeleton to membrane proteins, is present
