HRD1 Antibody

Western Blot: HRD1 Antibody [NB100-2526] - Detection of HRD1 in an endogenous 293T cell lysate.

Immunocytochemistry/Immunofluorescence: HRD1 Antibody [NB100-2526] - HRD1 antibody was tested in Hek293 cells with Dylight 488 (green). Nuclei and alpha-tubulin were counterstained with DAPI (blue) and Dylight 550 (red).

Immunohistochemistry-Paraffin: HRD1 Antibody [NB100-2526] - IHC analysis of a formalin fixed paraffin embedded (FFPE) tissue section of human tonsil using rabbit polyclonal HRD1 antibody at 2ug/ml concentration (1:500 dilution). The primary antibody binding to SYVN1/HRD1 antigen in cells was detected using HRP conjugated anti-Rabbit secondary antibody with DAB reagent, and the sections were further counterstained with hematoxylin for labeling cellular nuclei. This HRD1 antibody generated an expected cytoplasmic staining of HRD1 with stronger signal around periphery of the nucleus signifying the staining of the endoplasmic reticulum.

Background

HRD1 (synovial apoptosis inhibitor 1 or SYVN1) is a ubiquitin ligase whose expression is induced by UPR following ER stress and it provides protection to cells from apoptosis by inducing degradation of abnormally processed proteins that accumulate in ER. HRD1 acts as an E3 ubiquitin-protein ligase which accepts ubiquitin specifically from ER-associated UBC7 E2 ligase and transfers it to target proteins for promoting their degradation. It is a component of ER's quality control system called ERAD (ER-associated degradation) which is involved in ubiquitin-dependent degradation of misfolded ER proteins. HRD1 also facilitates the degradation of normal/naturally short-lived proteins such as SGK, and has been shown to protect neuronal cells from apoptosis triggered by polyglutamine-expanded huntingtin (HTT) or unfolded GPR37 by prooting their degradation. Moreover, HRD1 sequesters p53/TP53 in the cytoplasm and promotes its degradation, thereby negatively regulating its biological function in transcription, cell cycle regulation and apoptosis.
