Red blood cell spectrin, along with actin and several other proteins, forms a skeletal meshwork on the cytoplasmic surface of the erythrocyte plasma membrane. This structure is thought to maintain red blood cell shape, membrane structural stability, and cellular elasticity, as well as controlling the lateral mobility of integral membrane proteins and ...

Phosphorylation and dephosphorylation of spectrin
Journal of Supramolecular Structure, 1978AbstractThe phosphorylation of spectrin polypeptide 2 is thought to be involved in the metabolically dependent regulation of red cell shape and deformability. Spectrin phosphorylation is not affected by cAMP. The reaction in isolated membranes resembles the cAMP‐independent, salt‐stimulated phosphorylation of an exogenous substrate, casein, by enzyme(s)

Evolution of the spectrin repeat
BioEssays, 1997AbstractWe now know that the evolution of multidomain proteins has frequently involved genetic duplication events. These, however, are sometimes difficult to trace because of low sequence similarity between duplicated segments. Spectrin, the major component of the membrane skeleton that provides elasticity to the cell, contains tandemly repeated ...

AbstractFurther similarity between mammalian erythrocyte spectrin and pig brain spectrin has been demonstrated by (a) formation of hybrid molecules with brain α‐chains and erythrocyte β‐chains and by (b) identification of an ankyrin protein in brain membranes.

Brain α erythroid spectrin: identification, compartmentalization, and β spectrin associations
Brain Research, 1994Using isoform and subunit specific antibodies we have determined the presence, localization, and beta spectrin associations of alpha erythroid spectrin, alpha SpI sigma*, as well as alpha non-erythroid spectrin, alpha SpII sigma 1, in mouse brain. Peptide specific antibodies against unique sequences within the beta SpII sigma 1, non-erythroid beta ...

Summary. Spherocytic elliptocytosis is a phenotypic hybrid between hereditary spherocytosis (HS) and hereditary elliptocytosis (HE) characterized by the presence of spheroovalocytes and spherocytes which exhibit increased osmotic fragility, indicating a deficiency of surface area.

Spectrin: The ghost in the machine
BioEssays, 2001It has long been speculated that spectrin, the actin crosslinking and molecular scaffold protein, is involved in the development of apicobasal polarity in epithelia. While spectrins can undoubtedly influence the protein content of specific membrane domains, recent genetic evidence indicates that this activity is not necessary for the establishment or ...

Abstract First identified in the mammalian erythrocyte, spectrins are now recognized as ubiquitous proteins present in all metazoan organisms including plants. Because of this great diversity, a bewildering array of names, such as fodrin, calspectin, brain spectrin, spectrin G, lung spectrin, γ spectrin, 1W260/240, and so on, have been ...

Phospholipid suspensions prepared of phosphatidylethanolamine, phosphatidylserine and their mixtures are able to influence the intrinsic protein fluorescence of spectrin. In the case of phosphatidylethanolamine suspension up to 75% of protein fluorescence can be quenched.
