BAP, a Mammalian BiP-associated Protein, Is a Nucleotide Exchange Factor That Regulates the ATPase Activity of BiP. In addition,BAP was associated with BiP in mammalian cells and inter-acted with BiP functionallyin vitro. BAP stimulated the ATPase activity of BiP when added alone or together with the ER DnaJ protein, ERdj4, by promoting the release of ADP from BiP. Together, these data demonstrate that BAP serves as a nucleotide exchange factor for BiP and provide insights into the mechanisms that control protein folding in the mammalian ER. |

We showed that the molecular chaperone BiP (also known as GRP78) was short-lived under basal conditions and ER stress. The turnover of BiP was in part driven by its amino-terminal arginylation (Nt-arginylation) by the arginyltransferase ATE1, which generated an autophagic N-degron of the N-end rule pathway. |

Perturbation of the function of endoplasmic reticulum (ER) causes stress leading to the activation of cell signaling pathways known as the unfolded protein response (UPR). Severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) uses ER as a site for synthesis and processing of viral proteins. In this report, we demonstrate that infection with SARS-CoV induces the UPR in cultured cells. A comparison with M, E, and NSP6 proteins indicates that SARS-CoV spike (S) protein sufficiently induces transcriptional activation of several UPR effectors, including glucose-regulated protein 78 (GRP78), GRP94, and C/EBP homologous protein. |

We report here that glucose-regulated protein (GRP)-78, a critical regulator of the unfolded protein response (UPR), is a novel downstream target of BRCA1. We showed that overexpression of wild-type BRCA1 suppressed the expression of GRP78, whereas expression of mutant BRCA1 gene or targeted inhibition of endogenous BRCA1 using small-interfering RNA (siRNA) enhanced GRP78 expression. |

When BAP was added to BiP (2:1 molar ratio of BAP:BiP), it increased the ATPase activity of BiP by about 2-fold, which was similar to the increase observed when the J domain of ERdj4 was added to BiP (Fig.5). When both BAP and the J domain were added to BiP, the rate of ATP hydrolysis by BiP was stimulated by about 4-fold over basal levels, indicating that both BAP and ERdj4 positively regulate the ATPase activity of BiP |
