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.

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 ...

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.

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 ...

[8B7 spectrin--a new member of spectrin family].
Zhongguo yi xue ke xue yuan xue bao. Acta Academiae Medicinae Sinicae, 2007To analyze the nature of the protein encoded by 8B7cDNA (1 835 bp) and to examine the localization of the protein in cells.The nature of the protein was analyzed using Blastn, Blastp, and TMpred. Expressions of 8B7 mRNA in tissues and cells were examined by Northern blotting.

Analysis of the turnover of unassembled proteins during the assembly of the erythroid membrane skeleton has revealed that alpha- and beta-spectrin, two structurally related, high molecular weight proteins, are degraded in a selective manner by two distinct intracellular pathways. Unassembled alpha-spectrin (t1/2 approximately equal to 2 hr) is degraded

Binding of an 80 000 dalton trypsin fragment of spectrin to intact spectrin
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1982A specific and saturable interaction of an 80 000 dalton tryptic fragment of spectrin with intact spectrin has been detected. When spectrin was incubated with 125I-labelled 80 kDa fragment at 37 degrees C in the presence of 0.1 M NaCl, acrylamide gradient gel electrophoresis showed the presence of bands in addition to the usual spectrin dimer and ...

A Conformational Study of Human Spectrin
European Journal of Biochemistry, 1980Urea denaturation profiles of spectrin dimer, measured by circular dichroism in the regions of the peptide and aromatic Cotton effects, reflect the existence of several independently unfolding domains, as well as the presence of flexible, non‐globular structure.

Interaction of spectrin with hemin disaggregates spectrin associations.
Biochemistry international, 1984Crude spectrin preparations were extracted from red cell membranes either in dimeric or tetrameric forms and incubated at 4 degrees C with hemin. The mixtures were subjected immediately or after 18 hours to nondenaturing electrophoresis. It was found that immediately after addition of 0.3 mM hemin, the fraction of spectrin complexed with other skeletal
