Rabbit Anti-SYVN1/FITC Conjugated antibody
background:
This gene encodes a protein involved in endoplasmic reticulum (ER)-associated degradation. The encoded protein removes unfolded proteins, accumulated during ER stress, by retrograde transport to the cytosol from the ER. This protein also uses the ubiquitin-proteasome system for additional degradation of unfolded proteins. Sequence analysis identified two transcript variants that encode different isoforms. [provided by RefSeq, May 2011]
Function:
Acts as an E3 ubiquitin-protein ligase which accepts ubiquitin specifically from endoplasmic reticulum-associated UBC7 E2 ligase and transfers it to substrates, promoting their degradation. Component of the endoplasmic reticulum quality control (ERQC) system also called ER-associated degradation (ERAD) involved in ubiquitin-dependent degradation of misfolded endoplasmic reticulum proteins. Also promotes the degradation of normal but naturally short-lived proteins such as SGK. Protects cells from ER stress-induced apoptosis. Protects neurons from apoptosis induced by polyglutamine-expanded huntingtin (HTT) or unfolded GPR37 by promoting their degradation. Sequesters p53/TP53 in the cytoplasm and promotes its degradation, thereby negatively regulating its biological function in transcription, cell cycle regulation and apoptosis.
Subunit:
Homodimer. Interacts with p53/TP53 and HTT. Interacts with VCP, HERPUD1 and DERL1. Part of a complex containing SYVN1, HERPUD1, SELS and DERL1; which probably transfer misfolded proteins from the ER to VCP. Part of a complex containing SYVN1, SEL1L and DERL2. Interacts with UBXN6. Interacts with SEL1L; recruits ERLEC1 and OS9. May form a complex with ERLEC1; HSPA5; OS9 AND SEL1L.
Subcellular Location:
Endoplasmic reticulum membrane; Multi-pass membrane protein.
Tissue Specificity:
Ubiquitously expressed, with highest levels in liver and kidney (at protein level). Up-regulated in synovial tissues from patients with rheumatoid arthritis (at protein level).
Post-translational modifications:
Not N-glycosylated.
Auto-ubiquitinated.
Similarity:
Belongs to the HRD1 family.
Contains 1 RING-type zinc finger.
