Structural and functional analysis of transmembrane segment IV of the salt tolerance protein Sod2
Download2013-01-01
Ullah, Assad, Kemp, Grant, Lee, Brian, Alves, Claudia, Young, Howard, Sykes, Brian D., Fliegel, Larry
Sod2 is the plasma membrane Na+/H+ exchanger of the fission yeast Schizosaccharomyces pombe. It provides salt tolerance by removing excess intracellular sodium (or lithium) in exchange for protons. We examined the role of amino acid residues of transmembrane segment IV (TM IV)...

Structural and functional analysis of transmembrane segment VI of the NHE1 isoform of the na+/H+ exchanger
Download2009-01-01
Tzeng, Jennifer, Lee, Brian L., Sykes, Brian D., Fliegel, Larry
The Na+/H+ exchanger isoform 1 is a ubiquitously expressed integral membrane protein. It resides on the plasma membrane of cells and regulates intracellular pH in mammals by extruding an intracellular H+ in exchange for one extracellular Na+. We characterized structural and functional aspects of...

Structural and functional analysis of transmembrane XI of the NHE1 isoform of the na+/H+ exchanger
Download2009-01-01
Lee, Brian L., Li, Xiuju J., Liu, Yongsheng, Sykes, Brian D., Fliegel, Larry
The Na+/H+ exchanger isoform 1 is a ubiquitously expressed integral membrane protein that regulates intracellular pH in mammals by extruding an intracellular H+ in exchange for one extracellular Na+. We characterized structural and functional aspects of the critical transmembrane (TM) segment XI...

Structural and functional characterization of transmembrane segment IV of the NHE1 isoform of the na+/H+ exchanger
Download2005-01-01
Slepkov, Emily R., Rainey, Jan K., Li, Xiuju J., Liu, Yonghsheng S., Cheng, Florence J., Lindhout, Darrin A., Sykes, Brian D., Fliegel, Larry
The Na+/H+ exchanger isoform 1 is a ubiquitously expressed integral membrane protein that regulates intracellular pH in mammals. We characterized the structural and functional aspects of the critical transmembrane (TM) segment IV. Each residue was mutated to cysteine in cysteine-less NHE1. TM IV...

Structural and functional characterization of transmembrane segment IX of the NHE1 isoform of the na(+)/H(+) exchanger
Download2008-01-01
Reddy, Tyler, Ding, Jie, Li, Xiuju J., Sykes, Brian D., Rainey, Jan K., Fliegel, Larry
The Na+/H+ exchanger isoform 1 (NHE1) is an integral membrane protein that regulates intracellular pH by removing one intracellular H+ in exchange for one extracellular Na+. It has a large N-terminal membrane domain of 12 transmembrane segments and an intracellular C-terminal regulatory domain....

Structural and functional characterization of transmembrane segment VII of the na+/H+ exchanger isoform 1
Download2006-01-01
Ding, Jie, Rainey, Jan K., Xu, Caroline, Sykes, Brian D., Fliegel, Larry
The Na+/H+ exchanger isoform 1 is an integral membrane protein that regulates intracellular pH by exchanging one intracellular H+ for one extracellular Na+. It is composed of an N-terminal membrane domain of 12 transmembrane segments and an intracellular C-terminal regulatory domain. We...

Zarain-Herzberg, A., Fliegel, Larry, MacLennan, D. H.
We have isolated two overlapping 17-kilobase (kb) genomic clones which, together, encode the rabbit fasttwitch skeletal muscle calsequestrin. The calsequestrin gene is 8.6 kb in length and consists of 11 exons. Sl nuclease protection and primer extension analyses position the transcription...

The na+/H+ exchanger (NHE1) as a novel co-adjuvant target in paclitaxel therapy of triple-negative breast cancer cells
Download2015-01-01
Amith, Schammim Ray, Wilkinson, Jodi Marie, Baksh, Shairaz, Fliegel, Larry
Dysregulation of Na+/H+ exchanger isoform one (NHE1) activity is a hallmark of cells undergoing tumorigenesis and metastasis, the leading cause of patient mortality. The acidic tumor microenvironment is thought to facilitate the development of resistance to chemotherapy drugs and to promote...

Amith, Schammim Ray, Fliegel, Larry
Introduction: Triple-negative breast cancer, in which cells lack the expression of estrogen, progesterone, and human epidermal growth factor 2 receptors, is a clinical subtype of breast cancer commonly associated with poor prognosis. It tends to be aggressively metastatic with a high recurrence...

The Na+/H+ exchanger potentiates growth and retinoic acid induced differentiation of embryonal carcinoma cells
Download1997-01-01
Wang, Huayan, Singh, Dyal, Fliegel, Larry
The Na+/H+exchanger is a ubiquitous plasma membrane protein that is responsible for pH regulation and is activated by growth factors. We examined the role of the Na+/H+ exchanger in cell growth and differentiation. Treatment of P19 cells with the Na+/H+ exchanger inhibitor Hoe 694 eliminated...
