HSP70 family member GRP78 (78 kD glucose-regulated protein) is localized in ER lumen as well as melanosomes (stage I to stage IV) where it facilitates protein folding/assembly, protein quality control, Ca2+ binding, and regulates ER stress signaling. GRP78 interacts with DNAJC1 and is a component of EIF2 complex (CELF1/CUGBP1, CALR, CALR3, EIF2S1, EIF2S2, HSP90B1 and HSPA5) as well as chaperone multiprotein complex (DNAJB11, HSP90B1, HSPA5, HYOU, PDIA2, PDIA4, PDIA6, PPIB, SDF2L1, UGT1A1, ERP29). GRP78 also interacts with TMEM132A as well as TRIM21, and may form a complex with ERLEC1, OS9, SEL1L and SYVN1. In cancerous cells, GRP78 overexpression is associated with UPR activation, including upregulation of associated proteins such as PERK, ATF6, CHOP etc that further regulate JNK and NF-kB untimately leading to survival, tumor progression, angiogenesis, resistance to therapy and metastasis. GRP78 is a signaling receptor for activated alpha2-macroglobulin, plasminogen kringle 5, and microplasminogen, and plays role in viral entry of coxsackie B as well as dengue fever viruses. GRP78 is also involved in regulation of tissue factor procoagulant activity and functions as a receptor for angiogenic peptides via VEGFRs independent mechanism. Cell surface GRP78 is found associated with diverse proteins including VDAC, MHC-I, Cripto and DnaJ-like protein MTJ-1. Because GRP78 is present on the surface of cancer cells but not on normal cells in vivo, it provide an exciting opportunity for cancer targeting.

FAQs for GRP78/HSPA5 Antibody (NBP1-06274). (Showing 1 - 1 of 1 FAQs).

  1. I have received the Novus Cat # for a human GRP78-specific rabbit Ab from a lab that had used it and achieved some nice results with it. They suggest we use the same Ab to reproduce their data. However, I have not been able to find a product with that Cat # in your online search engine. Perhaps the product has been discontinued, or was given a different Cat #? Could you please look into this? The Ab they used was: GRP78 Cat # NBP1-49339, Lot # A113911. In case the product is no longer available, could you please recommend something that should be equivalent or very similar to it?
    • NBP1-49339 has been discontinued but NBP1-06274 uses a similar antigen that falls between amino acids 250 and 300 and works in Western blot and ICC. ICC and flow use essentially the same techniques, so it should work just fine if you were using it in flow or Western blot before.
