Overexpression of the 78-kDa glucose-regulated protein/immunoglobulin-binding protein (GRP78/BiP) inhibits tissue factor procoagulant activity.

Previous studies have demonstrated that overexpression of GRP78/BiP, an endoplasmic reticulum (ER)-resident molecular chaperone, in mammalian cells inhibits the secretion of specific coagulation factors. However, the effects of GRP78/BiP on activation of the coagulation cascade leading to thrombin generation are not known. In this study, we examined whether GRP78/BiP overexpression mediates cel...

Plasmodium falciparum gene encoding a protein similar to the 78-kDa rat glucose-regulated stress protein.

Genes homologous to heat shock protein 70 have been described in parasitic protozoa. It has been proposed that they may be important to the parasite as it moves from the vertebrate host at 37 degrees C to the insect. We now describe a genomic DNA clone isolated from Plasmodium falciparum that encodes a protein similar in sequence to a mammalian heat shock-related protein, the 78-kDa glucose-reg...

therapeutic potential of glucose regulated protein 78 in cancer

endoplasmic reticulum has a critical role in the synthesis and folding of secretory and membrane proteins. high accumulation of proteins in er activates the unfolded protein response and glucose regulated protein 78 or gpr78 plays an essential role in this pathway.  unfolded protein response is activated in cancerous cells due to their adverse condition to survive and it has been shown that grp...

Identification of a domain in apolipoprotein B-100 that inhibits the procoagulant activity of tissue factor.

The ability of low-density lipoprotein (LDL) to inhibit the procoagulant activity of tissue factor is mediated by a direct protein-protein interaction involving apolipoprotein (apo) B-100. A lysine-rich sequence within apo B-100 (residues 3121-3217), which we have termed lysine-rich apo B-100-derived (KRAD)-98 peptide, may be responsible for its activity. Within this region, residues 3147-3160 ...

Glucose-regulated protein 78 and platelet deposition: effect of rosuvastatin.

OBJECTIVE To investigate the effect of rosuvastatin on platelet deposition under controlled shear rate conditions and to identify new platelet proteins involved in the interaction with the activating substrate. METHODS AND RESULTS Platelet-vessel wall interaction and thrombosis take place under dynamic conditions involving the interaction of the exposed damaged vascular wall with the circulat...
