Modulation of voltage-dependent calcium channels by G proteins
Current Opinion in Neurobiology, 1998Voltage-gated calcium channels are found in all excitable cells, in which they regulate many important physiological functions, including excitability, gene transcription, muscle contraction, and neurotransmitter and hormone release. The differential modulation of calcium channels by intracellular second messengers constitutes a key mechanism for ...

Voltage-dependent calcium channels: structures and drug-binding sites
Biochemical Society Transactions, 1992I47 Tsien’s group classified these channels as ‘N, ‘T, In the 1960s the research groups of Fleckenstein and Godfraind defined ‘calcium antagonists’ as agents which blocked the entry of calcium into cells via voltage-dependent calcium channels. In a literature search we found 74 compounds in various stages of clinical or preclinical development classed ...

Effect of Aging on Brain Voltage-Dependent Calcium Channels
1993Control of interneuronal communication involves a variety of homeostatic mechanisms in which free calcium ions play a fundamental role (1). An altered metabolism of calcium in the brain that occurs with aging has been observed since the beginning of this century (2).

Voltage-Dependent and Receptor-Operated Calcium Channels
1995Contraction of airways smooth muscle is universally accepted as being the principal component of the acute phase of airflow limitation that characterizes an asthmatic attack. It is also acknowledged that the airway structure of asthmatic subjects is abnormal.

Structural properties of voltage-dependent calcium channels.
International review of cytology, 1993Following purification using Ca2+ channel drugs as ligands, the skeletal muscle Ca2+ channel was shown to be a five-subunit structure containing one large (175 kDa) protein that is the pore and four auxiliary subunits. Each subunit has been cloned and expression studies are proceeding rapidly.
