• Post Translation Modifications
• AMPylated by FICD.
  In unstressed cells, AMPylation at Thr-518 by FICD inactivates the chaperome activity: AMPylated form is locked in a relatively inert state and only weakly stimulated by J domain-containing proteins (By similarity).
  In response to endoplasmic reticulum stress, de-AMPylation by the same protein, FICD, restores the chaperone activity (By similarity).
  Glycosylation at Thr69, Thr203, and Thr643
  Ubiquitination at Lys96, Lys113, Lys118, Lys213, Lys268, Lys326, Lys370, Lys376, Lys523, Lys547, Lys573, and Lys601
  Modification sites at PhosphoSitePlus
  Glycosylation from GlyGen 6 sites, 2 O-linked glycans (5 sites)

• Protein Refseq
• NP_005338.1

• Function
• Acts as a key repressor of the ERN1/IRE1-mediated unfolded protein response (UPR) (PubMed:1550958, 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).
  Plays an auxiliary role in post-translational transport of small presecretory proteins across endoplasmic reticulum (ER).
  May function as an allosteric modulator for SEC61 channel-forming translocon complex, likely cooperating with SEC62 to enable the productive insertion of these precursors into SEC61 channel.
