EXCESS POTASSIUM INDUCES LARVAL METAMORPHOSIS IN FOUR MARINE INVERTEBRATE SPECIES
An increase in the concentration of K+ in defined seawater medium induces settlement and metamorphosis in larvae of the marine molluscs Phestilla sibogae, Haliotis rufescens, and Astraea undosa, andExpand

Inhibition of aquaporin-1 water permeability by tetraethylammonium: involvement of the loop E pore region.
Previously, the only known blockers of water permeability through aquaporin-1 (AQP1) water channels were mercurial reagents such as HgCl(2). For AQP1, inhibition by mercury has been attributed to theExpand

Cloning of a receptor for prostaglandin F2 alpha from the ovine corpus luteum.
A complementary DNA clone encoding a functional receptor for prostaglandin F2 alpha (PGF2 alpha) has been isolated from an ovine large luteal cell complementary DNA library (prepared from day 10Expand

Ion Channel Function of Aquaporin-1 Natively Expressed in Choroid Plexus
Aquaporins are known as water channels; however, an additional ion channel function has been observed for several including aquaporin-1 (AQP1). Using primary cultures of rat choroid plexus, a brainExpand

Identification and characterization of functional aquaporin water channel protein from alimentary tract of whitefly, Bemisia tabaci.
Some hemipteran xylem and phloem-feeding insects have evolved specialized alimentary structures or filter chambers that rapidly transport water for excretion or osmoregulation. In the whitefly,Expand

Alteration of ionic selectivity of a K+ channel by mutation of the H5 region
THE high ionic selectivity of K+ channels is a unifying feature of this diverse class of membrane proteins. Though K+ channels differ widely in regulation and kinetics, physiological studies haveExpand

Differential sensitivity of voltage-gated potassium channels Kv1.5 and Kv1.2 to acidic pH and molecular identification of pH sensor.
Kv1.2 and Kv1.5 are two subtypes of voltage-gated potassium channels expressed in heart that are thought to contribute to phase 1 (ITO) and phase 3 (IK) components of cardiac action potentialExpand

Single-channel K+ currents recorded from the somatic and dendritic regions of cerebellar Purkinje neurons in culture
Voltage-sensitive K+ channels were studied in rat cerebellar Purkinje neurons in culture using the single-channel recording technique. Recordings in the cell-attached and outside-out configurationExpand

Regulated Cationic Channel Function in XenopusOocytes Expressing Drosophila Big Brain
Big brain (bib) is a neurogenic gene that when mutated causes defects in cell fate determination duringDrosophila neurogenesis through an unknown mechanism. The protein Big Brain (BIB) has sequenceExpand

Mechanism of gating and ion conductivity of a possible tetrameric pore in aquaporin-1.
While substrate permeation through monomeric pores of aquaporins is well characterized, little is known about the possible tetrameric pore. AQP1 has been suggested to function as an ion channel uponExpand
