Orai proteins interact with TRPC channels and confer responsiveness to store depletion
- Yanhong Liao, C. Erxleben, E. Yildirim, J. Abramowitz, D. Armstrong, L. Birnbaumer
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 13 March 2007
The TRPC (C-type transient receptor potential) class of ion channels has been hypothesized to participate in store-operated Ca2+ entry (SOCE). Recently, however, STIM1 and Orai1 proteins have been… Expand
Functional interactions among Orai1, TRPCs, and STIM1 suggest a STIM-regulated heteromeric Orai/TRPC model for SOCE/Icrac channels
- Yanhong Liao, C. Erxleben, +4 authors L. Birnbaumer
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 26 February 2008
Receptor-operated Ca2+ entry (ROCE) and store-operated Ca2+ entry (SOCE) into cells are functions performed by all higher eukaryotic cells, and their impairment is life-threatening. The main… Expand
Voltage-activated calcium channels that must be phosphorylated to respond to membrane depolarization.

- 1 April 1987
Two classes of calcium channels were activated by membrane depolarization in cell-free membrane patches from GH3 cells, an electrically excitable cell line derived from a mammalian pituitary tumor.… Expand
Rac and Rho Mediate Opposing Hormonal Regulation of the Ether-A-Go-Go-Related Potassium Channel
- N. Storey, J. O’Bryan, D. Armstrong
- Biology, Medicine
- Current Biology
- 8 January 2002
BACKGROUND
Previous studies of ion channel regulation by G proteins have focused on the larger, heterotrimeric GTPases, which are activated by heptahelical membrane receptors. In contrast, studies of… Expand
Structure of a signal transduction regulator, RACK1, from Arabidopsis thaliana

- 1 October 2008
The receptor for activated C‐kinase 1 (RACK1) is a highly conserved WD40 repeat scaffold protein found in a wide range of eukaryotic species from Chlamydymonas to plants and humans. In tissues of… Expand
Rapid signaling at the plasma membrane by a nuclear receptor for thyroid hormone.
- N. Storey, S. Gentile, +4 authors D. Armstrong
- Biology, Medicine
- Proceedings of the National Academy of Sciences…
- 28 March 2006
Many nuclear hormones have physiological effects that are too rapid to be explained by changes in gene expression and are often attributed to unidentified or novel G protein-coupled receptors.… Expand
Stimulation of Kv1.3 Potassium Channels by Death Receptors during Apoptosis in Jurkat T Lymphocytes*
- N. Storey, M. Gómez-Angelats, C. Bortner, D. Armstrong, J. Cidlowski
- Biology, Medicine
- Journal of Biological Chemistry
- 29 August 2003
The loss of intracellular potassium is a pivotal step in the induction of apoptosis but the mechanisms underlying this response are poorly understood. Here we report caspase-dependent stimulation of… Expand
Conditional and Unconditional Inhibition of Calcium-activated Potassium Channels by Reversible Protein Phosphorylation*
- S. K. Hall, D. Armstrong
- Chemistry, Medicine
- The Journal of Biological Chemistry
- 11 February 2000
Large conductance, calcium-activated potassium channels (BKCa or maxi-K) are important determinants of membrane excitability in many cell types. We used patch clamp techniques to study the… Expand
