Cystic fibrosis (CF) is the most common lethal autosomal recessive disease in Caucasians, affecting an estimated 1 in 3, live-born infants (Davis et al., ).Affected individuals have variants in both copies of the kb CF transmembrane conductance regulator gene (CFTR), that result in significant reduction or absence of CFTR function.   Understanding the causes of variation in clinical manifestations of disease should allow for design of new or improved therapeutic strategies to treat the disease. If variation is caused by genetic differences between individuals, identifying the genes involved should present therapeutic targets, either in the proteins encoded by those genes or the pathways in which they by:

Abstract. This article focuses on activators and inhibitors of ClC ClC-2 Cl − channels from mouse, rabbit, rat, and human have been studied extensively in recombinant form by whole-cell patch-clamp and in single-channel studies.

There are similarities in responses of these channels from different species to protons, ATP, lipids, and lubiprostone for the recombinant by: 1.

Chloride channels are proteins that control cell membrane transport of chloride ions and hence modulate intestinal fluid secretion. Chloride channel openers, such as lubiprost are currently under development for the treatment of patients with constipation, IBS-C, and postoperative activating the specific chloride channel CIC2 in cells lining the gut, lubiprostone increases.

Chloride channels are a superfamily of poorly understood ion channels specific for channels may conduct many different ions, but are named for chloride because its concentration in vivo is much higher than other anions.

Several families of voltage-gated channels and ligand-gated channels (e.g., the CaCC families) have been characterized in ro: IPR The ClC-2 channel was identified as a target of regulation by the M phase-specific cyclin-dependent kinase p34cdc2/cyclin B; the C terminus of ClC-2 is directly phosphorylated by p34cdc2/cyclin B.

As a result, ClC-2 channel activities are inhibited by p34cdc2/cyclin B in Xenopus oocytes with ClC-2 overexpression [ 80 ].Cited by: Chloride channel activity of ClC-2 is modified by the actin cytoskeleton Article (PDF Available) in Biochemical Journal Pt 3(Pt 3) January with 39 Reads How we measure 'reads'.
