Abstract
The induction of human BiP/GRP78 and GAPDH protein genes by the calcium ionophore A23187 was determined. Steady-state levels of mRNA for both the glucose starvation-responsive BiP/GRP78 gene and the glucose-responsive GAPDH gene were dramatically induced in a variety of human cells. There is a homologous palindromatic sequence GCCGTTAACGGC in the active promoter region of the two genes that is known to be required for the induction of mammalian BiP/GRP78 by A23187. The evidence confirms in general the function of this element in the regulation of calcium-associated gene activity.
