Identification and Functional Characterization of a K1 Channel a- Subunit with Regulatory Properties Specific to Brain
(1997)
The physiological diversity of K1 channels mainly depends on the expression of several genes encoding different a-subunits. We have cloned a new K1 channel a-subunit (Kv2.3r) that is unable to form functional channels on ...

Thyrotropin-releasing-hormone (TRH) and its physiological metabolite TRH-OH inhibit Na+ channel activity in mammalian septal neurons
(1990)
The interaction of thyrotropin-releasing hormone (TRH) and its physiological metabolite TRH-OH with Na+ channels was studied in enzymatically dissociated guinea pig septal neurons by using the whole-cell variant of the ...

Orai1 and TRPC1 Proteins Co-localize with CaV1.2 Channels to Form a Signal Complex in Vascular Smooth Muscle Cells
(American Society for Biochemistry and Molecular Biology, 2016)
Voltage-dependent CaV1.2 L-type Ca2 channels (LTCC) are the main route for calcium entry in vascular smooth muscle cells (VSMC). Several studies have also determined the relevant role of store-operated Ca2 channels ...

A Small Domain in the N Terminus of the Regulatory a-Subunit Kv2.3 Modulates Kv2.1 Potassium Channel Gating
(1999)
Recent work has demonstrated the existence of regulatory K1 channel a-subunits that are electrically silent but capable of forming heterotetramers with other pore-forming subunits to modify their function. We have investigated ...

Brugada syndrome masked by complete left bundle branch block: A clinical and functional study of its association with the p.1449Y>H SCN5A variant
(Wiley Periodicals, LLC., 2021-07)
SCN5A gene variants are associated with both Brugada syndrome and conduction disturbances, sometimes expressing an overlapping phenotype. Functional consequences of SCN5A variants assessed by patch‐clamp electrophysiology ...

Complete loss of KCNA1 activity causes neonatal epileptic encephalopathy and dyskinesia
(BMJ Publishing Group, 2020)
Background: Since 1994, over 50 families affected by the episodic ataxia type 1 disease spectrum have been described with mutations in KCNA1, encoding the voltage-gated K+ channel subunit Kv1.1. All of these mutations are ...

Collapse of conductance Is prevented by a Glutamate residue conserved in voltage-dependent K+ channels
(2000)
Voltage-dependent K 1 channel gating is influenced by the permeating ions. Extracellular K 1 determines the occupation of sites in the channels where the cation interferes with the motion of the gates. When external [K 1] ...

Sodium and Calcium Currents in Dispersed Mammalian Septal Neurons
(1991)
Voltage-gated Na+ and Ca2+ conductances of freshly dissociated septal neurons were studied in the whole-cell configuration of the patch-clamp technique. All cells exhibited a large Na+ current with characteristic fast ...

Prolyl Hydroxylase-dependent Modulation of Eukaryotic Elongation Factor 2 Activity and Protein Translation under Acute Hypoxia
(American Society for Biochemistry and Molecular Biology, 2012-02-03)
Early adaptive responses to hypoxia are essential for cell survival, but their nature and underlying mechanisms are poorly known. We have studied the post-transcriptional changes in the proteome of mammalian cells elicited ...

PKCα-Mediated Downregulation of RhoA Activity in Depolarized Vascular Smooth Muscle: Synergistic Vasorelaxant Effect of PKCα and ROCK Inhibition
(2019-02-18)
Background/Aims: Protein kinase C (PKC)- and RhoA/Rho-associated kinase (ROCK) play important roles in arterial sustained contraction. Although depolarization-elicited RhoA/ROCK activation is accepted, the role of PKC ...
