  2. 21. Plasma Membrane Proteomics and Functional Characterization & Expression Profiling of Plant Aquaporins

    Author : Erik Alexandersson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; phosphorylation; barley; GFP; GUS; quantitative real-time reverse transcriptase PCR; microarray; aquaporin; MIP; Arabidopsis; plasma membrane; proteomics;

    Abstract : In order to identify integral and peripheral proteins associated with the plasma membrane (PM), highly purified Arabidopsis PMs were analyzed by mass spectrometry. In total, 238 putative PM proteins were identified, of which 114 were predicted to have transmembrane domains or to be PM-anchored. READ MORE

  4. 22. Nicotinic transmission and drugs in anesthesia : neuromuscular blocking agents and propofol : consequences for carotid body function

    Author : Malin Jonsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Carotid body; chemoreceptors; neuromuscular blocking agents; propofol; acetylcholine; nicotinic acetylcholine receptors;

    Abstract : The carotid body is the global oxygen sensor of the human body. Acute hypoxia elicits instant hyperventilation mediated from the carotid body type 1 cells, where nicotinic transmission is a key component in oxygen sensing and signalling. READ MORE

  5. 23. Molecular Mechanisms of Resin Acids and Their Derivatives on the Opening of a Potassium Channel

    Author : Nina Ottosson; Fredrik Elinder; David Engblom; Bertil Hille; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Voltage-gated ion channels play fundamental roles in excitable cells, such as neurons, where they enable electric signaling. Normally, this signaling is well controlled, but brain damage, alterations in the ionic composition of the extracellular solution, or dysfunctional ion channels can increase the electrical excitability thereby causing epilepsy.

  6. 24. Voltage sensor movements in shaker and HCN channels

    Author : Roope Männikkö; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Voltage-gated ion channels are crucial for electrical signaling in living organisms. They are composed of four similar subunits with six transmembrane α-helices, S1-S6. Each subunit contains a voltage-sensing domain, S1-S4, and an ion-conducting pore domain, S5-S6. READ MORE

  7. 25. Voltage-Sensor Domains of Ion Channels : Physiology, Regulation, and Role in Disease

    Author : Michelle Nilsson; Antonios Pantazis; Fredrik Elinder; Henry M. Colecraft; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Brain function depends on the ability of neurons to sense and respond to electricity, which is mediated by small modules in the neuronal membrane called voltage-sensor domains (VSDs). Disruption of VSD function can cause neurological disease such as epilepsy. READ MORE
