Dimeric structure of human na+/H+ exchanger isoform 1 overproduced in saccharomyces cerevisiae
Download2008-01-01
Moncoq, Karine, Kemp, Grant, Li, Xiuju J., Fliegel, Larry, Young, Howard S.
The Na+/H+ exchanger isoform 1 (NHE1) is an integral membrane protein that regulates intracellular pH by extruding an intracellular H+ in exchange for one extracellular Na+. The human NHE1 isoform is involved in heart disease and cell growth and proliferation. Although details of NHE1 regulation...

Regulation of Na+/H+ Exchanger Gene Expression: Role of a poly T rich region in regulation of expression of the NHE1 promoter
Download1996-01-01
Yang, Weidong, Wang, Huayan, Fliegel, Larry
In this study we examine regulation of expression of the Na+/H+ exchanger promoter in L6 and NIH 3T3 cells. We have identified a highly conserved poly(dA·dT)-rich region that appears to be important in regulation of expression of the NHE1 gene. Deletion or mutation of this region results in...

In this paper we examine the role of thyroid hormone in regulating expression of the Na+/H+ exchanger. Thyroid hormone has been reported to regulate the activity of the Na+/H+ exchanger messenger RNA in some cell types. Treatment of cardiac myocytes with 3,5′,3′-triiodothyronine results in an...
