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...

Regulation of Na+/H+ Exchanger Gene Expression: Role of a poly T rich region in regulation of expression of the NHE1 promoter

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...
