ABSTRACT CFTR chloride channels are encoded by the gene mutated in patients with cystic fibrosis. These channels belong to the superfamily of ABC transporter ATPases. ATP-driven conformational changes, which in other ABC proteins fuel uphill substrate transport across cellular membranes, in CFTR open and close a gate to allow transmembrane flow of anions down their electrochemical gradient. New structural and biochemical information from prokaryotic ABC proteins and functional information from CFTR channels has led to a unifying mechanism explaining those ATP-driven conformational changes.

    ABSTRACT: Anion receptors have attracted growing interest because of their role in chemistry, the environment, biology and medicine. The mis-regulation of anion flux causes a variety of lethal human diseases. Recently, triazole has been found to be an excellent motif for molecular recognition. This review depicts an overall picture of developments in the design and synthesis of anion receptors along with an up-to-date emphasis on the triazole unit as a motif for anion recognition. The acidic CH of triazole is involved in binding with the anions, which makes these receptors different from other classes of receptors. The chemo- and regio-selectivity of the click reaction provides further impetus for future developments in this area.

    ABSTRACT: Recent human clinical trials results demonstrated successful treatment for certain genetic forms of cystic fibrosis (CF). To extend treatment opportunities to those afflicted with other genetic forms of CF disease, structural and biophysical characterization of CF transmembrane conductance regulator (CFTR) is urgently needed. In this study, CFTR was modified with various tags, including a His10 purification tag, the SUMOstar (SUMO*) domain, an extracellular FLAG epitope, and an enhanced green fluorescent protein (EGFP), each alone or in various combinations. Expressed in HEK293 cells, recombinant CFTR proteins underwent complex glycosylation, compartmentalized with the plasma membrane, and exhibited regulated chloride-channel activity with only modest alterations in channel conductance and gating kinetics. Surface CFTR expression level was enhanced by the presence of SUMO* on the N-terminus. Quantitative mass-spectrometric analysis indicated approximately 10 % of the total recombinant CFTR (SUMO*-CFTR(FLAG)-EGFP) localized to the plasma membrane. Trial purification using dodecylmaltoside for membrane protein extraction reproducibly recovered 178 ± 56 μg SUMO*-CFTR(FLAG)-EGFP per billion cells at 80 % purity. Fluorescence size-exclusion chromatography indicated purified CFTR was monodisperse. These findings demonstrate a stable mammalian cell expression system capable of producing human CFTR of sufficient quality and quantity to augment future CF drug discovery efforts, including biophysical and structural studies.

    ABSTRACT: Scorpion venom is a complex multicomponent mixture of biologically active substances, some of which possess very interesting properties and are used in quite unexpected areas. The family of chlorotoxin (CTX)-like peptides is a good example. These toxins exhibit insecticidal activity, however, the molecular mechanism of their action on the insect organism has not been established yet. Nevertheless, CTX-like peptides attracted considerable research effort due to their ability to interact specifically with cells of malignant brain tumors—gliomas. In the future these compounds may significantly simplify treatment of tumor diseases. The review summarizes the results accumulated over a forty years period of CTX-like peptides study. Aspects of their natural functions are considered, as well as the application area associated with gliomas.
