GRP78 Antibody

Purified Rabbit Polyclonal Antibody (Pab)

     
  • WB - GRP78 Antibody AP50016
    Western blot analysis of lysates from Hela,HepG2 cell line (from left to right),using GRP78 Antibody(C0217). C0217 was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:5000 dilution was used as the secondary antibody.Lysates at 35ug per lane.
  • WB - GRP78 Antibody AP50016
    Western blot analysis of extracts from HUVEC cells (Lane 1), COS7 cells (Lane 2) and JK cells (Lane 3), using GRP78 Antibody. The lane on the left is treated with systhesized peptide.
  • IF - GRP78 Antibody AP50016
    Immunofluorescence analysis of COS7 cells, using GRP78 antibody .
  • IHC - GRP78 Antibody AP50016
    Immunohistochemical analysis of paraffin-embedded human breast carcinoma tissue using GRP78 antibody .

Protein Information
Name HSPA5 (HGNC:5238)
Function Endoplasmic reticulum chaperone that plays a key role in protein folding and quality control in the endoplasmic reticulum lumen (PubMed:2294010, PubMed:23769672, PubMed:23990668, PubMed:28332555). Involved in the correct folding of proteins and degradation of misfolded proteins via its interaction with DNAJC10/ERdj5, probably to facilitate the release of DNAJC10/ERdj5 from its substrate (By similarity). Acts as a key repressor of the ERN1/IRE1-mediated unfolded protein response (UPR) (PubMed:1550958, PubMed:19538957). In the unstressed endoplasmic reticulum, recruited by DNAJB9/ERdj4 to the luminal region of ERN1/IRE1, leading to disrupt the dimerization of ERN1/IRE1, thereby inactivating ERN1/IRE1 (By similarity). Accumulation of misfolded protein in the endoplasmic reticulum causes release of HSPA5/BiP from ERN1/IRE1, allowing homodimerization and subsequent activation of ERN1/IRE1 (By similarity).
Cellular Location Endoplasmic reticulum lumen Melanosome. Cytoplasm {ECO:0000250|UniProtKB:P20029}. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV

Background

Probably plays a role in facilitating the assembly of multimeric protein complexes inside the endoplasmic reticulum. Involved in the correct folding of proteins and degradation of misfolded proteins via its interaction with DNAJC10, probably to facilitate the release of DNAJC10 from its substrate.
