Guanosine 5'-triphosphate releases calcium from rat liver and guinea pig parotid gland endoplasmic reticulum independently of inositol 1,4,5-trisphosphate.

V Henne, H D Söling.   

Abstract

GTP releases calcium from rat liver microsomes and guinea pig parotid gland microsomal subfractions independently of the presence of inositol 1,4,5-trisphosphate (IP3). Non-hydrolyzable guanine nucleotide analogues have no effect and inhibit the effect of GTP. The mechanism of GTP-mediated calcium release differs from IP3-mediated calcium release as indicated by the following findings: GTP-induced calcium release depends on the presence of compounds which increase the viscosity of the medium (polyethylene glycol, polyvinylpyrrolidone, or bovine serum albumin); GTP-mediated calcium release is much slower; GTP-mediated calcium release is strongly temperature-dependent, whereas IP3-mediated calcium release is not; GTP-mediated calcium release is much more sensitive to a decrease of intravesicular free calcium than IP3-mediated calcium release.
