Routes of Protein Kinase A. Physiol Rev 84: 137–167, 2004; 10.1152/physrev. 00021.2003 …

Voltage-sensitive ion channels mediate action potentials in electrically excitable cells and
play important roles in signal transduction in other cell types. In the past several years, their …

Voltage-gated L-type Ca2+ channels mediate Ca2+ entry into cells in response to
membrane depolarization. Ca2+ entry through the cardiac Ca2+ channel determines the …

Our aim is to describe the acute effects of catecholamines/β‐adrenergic agonists on
contraction of non‐fatigued skeletal muscle in animals and humans, and explain the …

THE force of contraction of motor units in skeletal muscle is graded by changing the
discharge rate of motor neurons1, and cytosolic calcium transients are similarly increased2 …

Subcellular targeting of the cAMP-dependent protein kinase is achieved, in part, through
association with A-kinase anchoring proteins (AKAPs). Recent evidence suggests that …

Rapid, voltage-dependent potentiation of skeletal muscle L-type calcium channels requires
phosphorylation by cAMP-dependent protein kinase (PKA) anchored via an A kinase …

The molecular properties of two size forms of the alpha 1 subunit of purified skeletal muscle
calcium channels were analyzed. The minor, full-length, form, alpha 1 (212), was found to …

It is well recognized that calcium (Ca) is an important regulatory element for many cellular
processes. In most eukaryotic cells a diverse array of Ca transporting systems functions to …
