GRP94 in cerebrospinal fluid may contribute to a potential biomarker of depression: Based on proteomics.
Title: GRP94 in cerebrospinal fluid may contribute to a potential biomarker of depression: Based on proteomics.
We found that GRP94 coimmunoprecipitated with proinsulin and that inhibition of GRP94 function and/or expression reduced glucose-dependent insulin secretion, shortened proinsulin half-life, and lowered intracellular proinsulin and insulin levels.
Title: Endoplasmic Reticulum Chaperone Glucose-Regulated Protein 94 Is Essential for Proinsulin Handling.
We demonstrated that incubation of hepatocytes for 16 h with palmitic acid elevated cell death. Moreover, Western blot analyses demonstrated increased levels of the endoplasmic reticulum stress markers - glucose regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), and glucose regulated protein 94 (GRP94).
Title: Chlorogenic acid against palmitic acid in endoplasmic reticulum stress-mediated apoptosis resulting in protective effect of primary rat hepatocytes.
The results showed that both Unfolded Protein Response (Xbp-1, its spliced variant sXbp-1, Atf-6, Chop, and Grp94) and Toll like receptor (2, 3, 4, 7 and 9) genes were significantly upregulated in the hippocampi of rats who were exposed to restraint stress.
Title: Unfolded protein response and associated alterations in toll-like receptor expression and interaction in the hippocampus of restraint rats.
The maintenance of Grp94 expression is sufficient to counter unloading atrophy and oxidative stress by mechanistically stabilizing nNOS-multiprotein complex at the myofiber sarcolemma.
Title: The stress protein/chaperone Grp94 counteracts muscle disuse atrophy by stabilizing subsarcolemmal neuronal nitric oxide synthase.
Hepatic expression of metallothionein I/II, glycoprotein 96, IL-6, and TGF- beta in rat strains contributed to different susceptibilities to experimental autoimmune encephalomyelitis.

gp96 might be involved in proteostasis and immune-related pathways linked with the reparative processes in the central nervous system
Title: Expression pattern of the endoplasmic reticulum stress protein gp96 in monophasic and chronic relapsing form of experimental autoimmune encephalomyelitis in rats.
GRP94 immunoactivity is expressed at low levels in gray matter and white matter in normal condition and increased after spinal cord injury.
Title: Overexpression of glucose-regulated protein 94 after spinal cord injury in rats.
Results indicate that Grp94 can activate the humoral response by a cytokine-like, cell-mediated mechanism that leads to an accelerated process of B cell maturation and differentiation.
Title: Effects of glucose-regulated protein94 (Grp94) on Ig secretion from human blood mononuclear cells.
gp96 can act as a costimulatory molecule for CD3+ T cells, and an observed increase in the IL-10: IFN-gamma secretion ratio induced by gp96 suggests that it might, at appropriate concentrations, promote a regulatory T-helper 2 (Th2)-like phenotype.
Title: The stress protein gp96 is not an activator of resting rat bone marrow-derived dendritic cells, but is a costimulator and activator of CD3+ T cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
