    Description: Dihydropyridine-sensitive voltage-dependent L-type calcium channels are critical to excitation-secretion and excitation-contraction coupling. The channel molecule is a complex of the main, pore-forming subunit alpha 1 and four additional subunits: alpha 2, delta, beta, and gamma (alpha 2 and delta are encoded by a single messenger RNA). The alpha 1 subunit messenger RNA alone directs expression of functional calcium channels in Xenopus oocytes, and coexpression of the alpha 2/delta and beta subunits enhances the amplitude of the current. The alpha 2, delta, and gamma subunits also have pronounced effects on its macroscopic characteristics, such as kinetics, voltage dependence of activation and inactivation, and enhancement by a dihydropyridine agonist. In some cases, specific modulatory functions can be assigned to individual subunits, whereas in other cases the different subunits appear to act in concert to modulate the properties of the channel.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Singer, D -- Biel, M -- Lotan, I -- Flockerzi, V -- Hofmann, F -- Dascal, N -- New York, N.Y. -- Science. 1991 Sep 27;253(5027):1553-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Pharmacology, Sackler School of Medicine, Tel Aviv University, Ramat Aviv, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1716787" target="_blank"〉PubMed〈/a〉

    Description: Complementary DNAs for the beta subunit of the dihydropyridine-sensitive calcium channel of rabbit skeletal muscle were isolated on the basis of peptide sequences derived from the purified protein. The deduced primary structure is without homology to other known protein sequences and is consistent with the beta subunit being a peripheral membrane protein associated with the cytoplasmic aspect of the sarcolemma. The protein contains sites that might be expected to be preferentially phosphorylated by protein kinase C and guanosine 3',5'-monophosphate-dependent protein kinase. A messenger RNA for this protein appears to be expressed in brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ruth, P -- Rohrkasten, A -- Biel, M -- Bosse, E -- Regulla, S -- Meyer, H E -- Flockerzi, V -- Hofmann, F -- New York, N.Y. -- Science. 1989 Sep 8;245(4922):1115-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Physiologische Chemie, Medizinische Fakultat, Homburg/Saar, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549640" target="_blank"〉PubMed〈/a〉

    Description: Retinitis pigmentosa refers to a diverse group of hereditary diseases that lead to incurable blindness, affecting two million people worldwide. As a common pathology, rod photoreceptors die early, whereas light-insensitive, morphologically altered cone photoreceptors persist longer. It is unknown if these cones are accessible for therapeutic intervention. Here, we show that expression of archaebacterial halorhodopsin in light-insensitive cones can substitute for the native phototransduction cascade and restore light sensitivity in mouse models of retinitis pigmentosa. Resensitized photoreceptors activate all retinal cone pathways, drive sophisticated retinal circuit functions (including directional selectivity), activate cortical circuits, and mediate visually guided behaviors. Using human ex vivo retinas, we show that halorhodopsin can reactivate light-insensitive human photoreceptors. Finally, we identified blind patients with persisting, light-insensitive cones for potential halorhodopsin-based therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Busskamp, Volker -- Duebel, Jens -- Balya, David -- Fradot, Mathias -- Viney, Tim James -- Siegert, Sandra -- Groner, Anna C -- Cabuy, Erik -- Forster, Valerie -- Seeliger, Mathias -- Biel, Martin -- Humphries, Peter -- Paques, Michel -- Mohand-Said, Saddek -- Trono, Didier -- Deisseroth, Karl -- Sahel, Jose A -- Picaud, Serge -- Roska, Botond -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):413-7. doi: 10.1126/science.1190897.

    Description: Ebola virus causes sporadic outbreaks of lethal hemorrhagic fever in humans, but there is no currently approved therapy. Cells take up Ebola virus by macropinocytosis, followed by trafficking through endosomal vesicles. However, few factors controlling endosomal virus movement are known. Here we find that Ebola virus entry into host cells requires the endosomal calcium channels called two-pore channels (TPCs). Disrupting TPC function by gene knockout, small interfering RNAs, or small-molecule inhibitors halted virus trafficking and prevented infection. Tetrandrine, the most potent small molecule that we tested, inhibited infection of human macrophages, the primary target of Ebola virus in vivo, and also showed therapeutic efficacy in mice. Therefore, TPC proteins play a key role in Ebola virus infection and may be effective targets for antiviral therapy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4550587/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4550587/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sakurai, Yasuteru -- Kolokoltsov, Andrey A -- Chen, Cheng-Chang -- Tidwell, Michael W -- Bauta, William E -- Klugbauer, Norbert -- Grimm, Christian -- Wahl-Schott, Christian -- Biel, Martin -- Davey, Robert A -- R01 AI063513/AI/NIAID NIH HHS/ -- R01AI063513/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2015 Feb 27;347(6225):995-8. doi: 10.1126/science.1258758.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Texas Biomedical Research Institute, San Antonio, TX, USA. ; The University of Texas Medical Branch, Galveston, TX, USA. ; Center for Integrated Protein Science Munich (CIPSM) at the Department of Pharmacy-Center for Drug Research, Ludwig-Maximilians-Universitat Munchen, Munich, Germany. ; Southwest Research Institute, San Antonio, TX, USA. ; Institute for Experimental and Clinical Pharmacology and Toxicology, Albert-Ludwigs-Universitat Freiburg, Freiburg, Germany. ; Texas Biomedical Research Institute, San Antonio, TX, USA. rdavey@txbiomed.org.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25722412" target="_blank"〉PubMed〈/a〉

    Notes: [Auszug] In the mammalian retina, besides the conventional rod–cone system, a melanopsin-associated photoreceptive system exists that conveys photic information for accessory visual functions such as pupillary light reflex and circadian photo-entrainment. On ablation of the melanopsin gene, ...
