Abstract
Protein 4.1R plays an important role in maintaining the mechanical properties of the erythrocyte membrane. We analysed the expression of Kell blood group protein in erythrocytes from a patient with hereditary elliptocytosis associated with complete 4.1R deficiency (4.1(-) HE). Flow cytometry and Western blot analyses revealed a severe reduction of Kell. In vitro pull down and co-immunoprecipitation experiments from erythrocyte membranes showed a direct interaction between Kell and 4.1R. Using different recombinant domains of 4.1R and the cytoplasmic domain of Kell, we demonstrated that the R(46) R motif in the juxta-membrane region of Kell binds to lobe B of the 4.1R FERM domain. We also observed that 4.1R deficiency is associated with a reduction of XK and DARC (also termed ACKR1) proteins, the absence of the glycosylated form of the urea transporter B and a slight decrease of band 3. The functional alteration of the 4.1(-) HE erythrocyte membranes was also determined by measuring various transport activities. We documented a slower rate of HCO3 (-) /Cl(-) exchange, but normal water and ammonia transport across erythrocyte membrane in the absence of 4.1. These findings provide novel insights into the structural organization of blood group antigen proteins into the 4.1R complex of the human red cell membrane.

Abstract
The spectrin-based membrane skeleton of the humble mammalian erythrocyte has provided biologists with a set of interacting proteins with diverse roles in organization and survival of cells in metazoan organisms. This review deals with the molecular physiology of spectrin, ankyrin, which links spectrin to the anion exchanger, and two spectrin-associated proteins that promote spectrin interactions with actin: adducin and protein 4.1. The lack of essential functions for these proteins in generic cells grown in culture and the absence of their genes in the yeast genome have, until recently, limited advances in understanding their roles outside of erythrocytes. However, completion of the genomes of simple metazoans and application of homologous recombination in mice now are providing the first glimpses of the full scope of physiological roles for spectrin, ankyrin, and their associated proteins. These functions now include targeting of ion channels and cell adhesion molecules to specialized compartments within the plasma membrane and endoplasmic reticulum of striated muscle and the nervous system, mechanical stabilization at the tissue level based on transcellular protein assemblies, participation in epithelial morphogenesis, and orientation of mitotic spindles in asymmetric cell divisions. These studies, in addition to stretching the erythrocyte paradigm beyond recognition, also are revealing novel cellular pathways essential for metazoan life. Examples are ankyrin-dependent targeting of proteins to excitable membrane domains in the plasma membrane and the Ca(2+) homeostasis compartment of the endoplasmic reticulum. Exciting questions for the future relate to the molecular basis for these pathways and their roles in a clinical context, either as the basis for disease or more positively as therapeutic targets.

Abstract
The inositol hexaphosphate (IHP) method for purification of the erythrocyte membrane protein 4.1 yields the largest quantity of pure protein of any published protocol. However, protein 4.1 isolated by this method was found to bind to KI-stripped inside-out red blood cell membrane vesicles (KIOVs) only 40% as well as protein 4.1 purified by other methods. While an improved Tyler method, the SP method, yields 30-40% less protein 4.1 than the IHP method, the SP preparation nevertheless exceeds the IHP method in that the protein 4.1 is fully functional. Unlike the Tyler method, the SP procedure is also free of contaminating spectrin, p55, and proteases.

Abstract
Human immunoglobulins (IgG) are produced on a multi-ton scale for therapeutic applications. There is presently no available method to manufacture IgG preparations enriched with immunoglobulins from the IgG2 subclass although they might be useful for therapeutic purposes. By frontal chromatography, we have screened 69 immobilized dyes, among which, six display a different affinity for IgG2 and other subclasses. One (Procion Yellow HE-4R) was studied further. The screening of various mobile phase conditions allowed us to devise a procedure to prepare IgG2 enriched IgG solutions: The cumulative yield for IgG2 was 43% and IgG2/total IgG ratio in the final product was 67%.

Abstract
All methods of protein separations can be applied to proteases. Some emphasis is put in this review on a powerful technique specific to proteases purification: cyclic peptide antibiotics may be seen as general affinity ligands for proteases. Also, some examples of affinity chromatography of proteases on ligands with narrower specificity are given. The special interest of hydrophobic interaction chromatography for proteases purification is discussed. The merits of immobilized dye chromatography for proteases purification and the interest in empirically screening many immobilized dyes, as well as several eluents are discussed.

Abstract
Diphosphoinositol pentakisphosphate (PP-IP5) and bis(diphospho)inositol tetrakisphosphate (bis-PP-IP4) are recently identified inositol phosphates that possess pyrophosphate bonds. We have purified an inositol hexakisphosphate (IP6) kinase from rat brain supernatants. The pure protein, a monomer of 54 kDa, displays high affinity (Km = 0.7 microM) and selectivity for inositol hexakisphosphate as substrate. It can be dissociated from bis(diphospho)inositol tetrakisphosphate synthetic activity. The purified enzyme transfers a phosphate from PP-IP5 to ADP to form ATP. This ATP synthase activity indicates the high phosphate group transfer potential of PP-IP5 and may represent a physiological role for PP-IP5.

Abstract
Protein 4.1 has been defined as a major component of the subcortical skeleton of erythrocytes. It binds the spectrin--actin scaffold through a 10-kD internal domain. This binding requires an essential 21-amino acid sequence motif, Motif I, which is retained by alternative splicing at the late stage of erythroid differentiation. We here analyze the molecular basis of heterozygous 4.1(-) hereditary elliptocytosis, associated with protein 4.1 partial deficiency, in nine related French families. cDNA sequencing revealed a single codon deletion (AAA) resulting in a lysine residue deletion within the 10-kD binding domain, 3' of Motif I. The mutated allele was designated allele 4.1 Aravis. In order to assess the functional effect of the codon deletion, recombinant 10-kD constructs were made and various binding assays were performed using spectrin, purified spectrin-actin complex, or red cell membranes. These experiments demonstrated that the deletion of the Lys residue clearly prevents the binding capacity. Similar results were obtained with a construct containing the Lys residue but lacking Motif I. These data strongly suggest that the binding site to the spectrin-actin complex must contain the Lys 447 (or 448), and therefore resides not only on Motif I but extends 3' of this essential motif.

Abstract
The formation of neurofibrillary tangles (NFTs) and paired-helical filaments (PHFs) in Alzheimer's disease (AD) reflects a major disorganization of the cytoskeleton. The role of the neuronal membrane skeleton in the development of these abnormalities has not previously been investigated. In this study, we used 9 antibodies raised against the erythrocyte membrane skeleton protein 4.1 (P4.1) for immunocytochemical and immunoblot analyses to investigate whether or not the brain homologues of this protein were constituents of NFTs or PHFs. Our results show that 7 of the 9 monospecific antibodies against the human and pig erythrocyte P4.1 stained NFTs in the prefrontal cortex and hippocampus of AD brains. The P4.1 antibodies used here did not cross-react with tau protein isolated from AD brain, and preabsorption of these antibodies with tau protein did not cause loss of NFT staining. In age-matched control brains, these P4.1 antibodies stained neuronal cell bodies or nuclei. Six of the antibodies also stained isolated NFTs but the SDS-insoluble NFTs were immunostained only by two of the P4.1 antibodies. By using inositol hexaphosphate affinity chromatography and immunoblot analysis, we identified a 68-kDa protein as the most likely brain analogue of P4.1. When SDS-extracted proteins from the isolated NFTs were immunoblotted, a 50-kDa band was immunostained. The 68-kDa and 50-kDa proteins were not stained by tau protein and neurofilament subunit NF-H antibodies, that strongly stained NFTs. We conclude that brain protein 4.1 isoform(s) are constituents of NFTs in AD.

Abstract
A range of substances were screened to find eluents for human immunoglobulin G (IgG) which are retained with a strong affinity by immobilized Drimarene Rubine R/K-5BL. The strong affinity of IgG for the dye is partly due to the presence of copper in the dye. This was suggested by the effect of substances able to make coordination bonds with metals that elute the IgG and also the effect of metal stripping from the immobilized dye. Several mobile phase conditions were found that allowed desorption of retained IgG on immobilized Drimarene Rubine R/K-5BL without using a protein denaturant. A procedure was also devised for separating IgG2 from other IgG subclasses using chromatography on immobilized Rubine R/K-5BL and column development with an AMP gradient.
