Access to health care should be determined by clinical need and not by age. Older people form an increasing proportion of the general population and of those with coronary heart disease, but compared with younger people they are less likely to be invited for cardiac rehabilitation programmes and...

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...

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...

Mitogen-activated protein kinase-dependent activation of the na+/H+ exchanger is mediated through phosphorylation of amino acids ser(770) and ser(771)

Malo, Mackenzie E., Li, Liang, Fliegel, Larry
We investigated regulation of the type 1 isoform of the Na+/H+ exchanger by phosphorylation. Four specific groups of serine and threonine residues in the regulatory carboxyl-terminal tail were mutated to alanine residues: group 1, S693A; group 2, T718A and S723A/S726A/S729A; group 3,...

COUP-TF1 antagonizes Nkx25-mediated activation of the calreticulin gene during cardiac development

Guo, Lei, Lynch, Jeffrey, Nakamur, Kimitoshi, Fliegel, Larry, Kasahara, Hideko, Izumo, Seigo, Komuro, Issei, Agellon, Luis B., Michalak, Marek
Calreticulin, a Ca2+ binding chaperone of the endoplasmic reticulum, is also highly expressed in the embryonic heart, and knockout of the calreticulin gene is lethal during embryogenesis because of impaired cardiac development. The protein is down-regulated after birth, and elevated expression of...

Dyck, Jason, Silva, Norma Lucena C. L., Fliegel, Larry
We have isolated and characterized regions important for expression of the mouse NaGraphic/HGraphic exchanger gene. A 1.1-kilobase fragment upstream of the 5′-untranslated region contains specific DNA motifs characteristic of promoter and enhancer elements including a TATA box, two CAAT boxes, an...
