VDAC, a Channel in the Outer Mitochondrial Membrane,displays complex behavior. It has two voltage-gating processes, can be controlled by metabolites and regulatory proteins, is able to form complexes with other proteins and enzymes, and responds to the protein concentration of the cytoplasm (Colombini, 1994). Thus, many functions are packed into a si

Developing Three-Dimensional Models of Ion Channel Proteins,this class there is a wide variety of structures and functions. For example, the types of proteins reviewed here include antibiotics, toxins, molecular sieves, a shark repellent, and the voltage- and ligand-gated types of channels responsible for electrical conduction in the nervous system. The size

Structural and Functional Diversity of Voltage-Activated Calcium Channels,coded by the quantitative contribution and properties of the ion channels underlying both the action potential and the events that follow. As such, voltage-dependent Ca. channels represent one class of these ion channels that have both a remarkable ubiquity and importance in a variety of cell types.

Structure and Regulation of the Amiloride-Sensitive Epithelial Sodium Channel,odiffusion of sodium through the apical membrane with active extrusion of intracellular sodium by Na./K./ATPases present in the basolateral membrane generates active Na. reabsorption via a transcellular pathway (Palmer, 1992; Eaton and Hamilton, 1988; Garty and Benos, 1986). The rate-limiting factor

VDAC, a Channel in the Outer Mitochondrial Membrane,protein is the 2-MDa ryanodine receptor while the smallest may be gramicidin. However, the size of the conducting pathway is not correlated with the amount of protein mass needed to make up the structure, as demonstrated by the fact that some of the narrowest conducting pathways are produced by very

Albumin

Calcium-Activated Potassium Channels in Adrenal Chromaffin Cells,difying the electrical behavior of virtually all cells that express such channels (Rudy, 1988; Covar-rubias ., 1991). As a consequence of differences in the rates and voltage dependence of activation, deactivation, and inactivation, various K.-selective channels determine a variety of cellular elect

Regulation of Calcium Release Channel in Sarcoplasmic Reticulum,in response to an electrical signal from the motor nerve. However, the mechanism underlying the Ca. release from SR has remained unresolved (Ashley ., 1991; Endo, 1977; Martonosi, 1984; Meissner, 1994; Williams, 1992). Recently, the Ca.-induced Ca. release channel was isolated as a ryanodine recepto
