NCBI Summary
This gene encodes a resident endoplasmic reticulum (ER) protein that functions in N-glycan recognition. This protein is thought to be involved in ER-associated degradation via its interaction with the membrane-associated ubiquitin ligase complex. It also functions as a regulator of multiple cellular stress-response pathways in a manner that promotes metastatic cell survival. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 21. [provided by RefSeq, Aug 2011].

Structural models
AlphaFold v2: AF-Q96DZ1-F1Download
  Model Confidence:
  •    Very high (pLDDT > 90)
  •    Confident (90 > pLDDT > 70)
  •    Low (70 > pLDDT > 50)
  •    Very low (pLDDT < 50)

  AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Oligomerization and Known Interactions
May form a complex with OS9, HSPA5, SYVN1, and SEL1L with which it interacts directly. Interacts (via PRKCSH 2 domain) with KREMEN2 (when glycosylated). Interacts with HSPA5. Source: UniProt
