Sodium-calcium exchange: a molecular perspective.
Plasma membrane Na(+)-Ca2+ exchange is an essential component of Ca2+ signaling pathways in several tissues. Activity is especially high in the heart where the exchanger is an important regulator ofExpand

Molecular cloning and functional expression of the cardiac sarcolemmal Na(+)-Ca2+ exchanger
The Na(+)-Ca2+ exchanger of the cardiac sarcolemma can rapidly transport Ca2+ during excitation-contraction coupling. To begin molecular studies of this transporter, polyclonal antibodies were usedExpand

Tissue specificity and alternative splicing of the Na+/Ca2+ exchanger isoforms NCX1, NCX2, and NCX3 in rat.
The gene coding for the Na+/Ca2+ exchanger NCX1 is characterized by a cluster of six exons (A, B, C, D, E, and F) coding for a variable region in the COOH terminus of the large intracellular loop ofExpand

Cloning of a Third Mammalian Na+-Ca2+ Exchanger, NCX3*
NCX3 is the third isoform of a mammalian Na+-Ca2+ exchanger to be cloned. NCX3 was identified from rat brain cDNA by polymerase chain reaction (PCR) using degenerate primers derived from theExpand

Cloning of the NCX2 isoform of the plasma membrane Na(+)-Ca2+ exchanger.
The Na(+)-Ca2+ exchanger is an important regulator of cellular Ca2+ levels, and one isoform of this transporter, NCX1, has been cloned previously (Nicoll, D.A., Longoni, S., and Philipson, K.D.Expand

Allosteric Regulation of Na/Ca Exchange Current by Cytosolic Ca in Intact Cardiac Myocytes
The cardiac sarcolemmal Na-Ca exchanger (NCX) is allosterically regulated by [Ca]i such that when [Ca]i is low, NCX current (INCX) deactivates. In this study, we used membrane potential (Em) and INCXExpand

Molecular Cloning of a Third Member of the Potassium-dependent Sodium-Calcium Exchanger Gene Family,NCKX3 *
We describe here the identification and characterization of a novel member of the family of K+-dependent Na+/Ca2+ exchangers, NCKX3(gene SLC24A3). Human NCKX3 encodes a protein of 644 amino acidsExpand

Functional comparison of the three isoforms of the Na+/Ca2+ exchanger (NCX1, NCX2, NCX3).
Three distinct mammalian Na+/Ca2+exchangers have been cloned: NCX1, NCX2, and NCX3. We have undertaken a detailed functional comparison of these three exchangers. Each exchanger was stably expressedExpand

Identification of a peptide inhibitor of the cardiac sarcolemmal Na(+)-Ca2+ exchanger.
The deduced amino acid sequence of the cardiac sarcolemmal Na(+)-Ca2+ exchanger has a region which could represent a calmodulin binding site. As calmodulin binding regions of proteins often have anExpand

Regulation of the cardiac Na(+)-Ca2+ exchanger by Ca2+. Mutational analysis of the Ca(2+)-binding domain
The sarcolemmal Na(+)-Ca2+ exchanger is regulated by intracellular Ca2+ at a high affinity Ca2+ binding site separate from the Ca2+ transport site. Previous data have suggested that the Ca2+Expand
