Endoplasmic reticulum chaperone BiP homolog; Endoplasmic reticulum chaperone that plays a key role in protein folding and quality control in the endoplasmic reticulum lumen (By similarity). Required for ER dynamics during the first embryonic cell divisions. Specifically, controls ER transition into sheet-like structures at the onset of mitosis, possibly by regulating homotypic membrane fusion. Belongs to the heat shock protein 70 family.

Uncharacterized protein.

Endoplasmin homolog; Molecular chaperone that functions in the processing and transport of secreted proteins; Belongs to the heat shock protein 90 family.

DnaJ homolog dnj-10.

J domain-containing protein.

Calreticulin; Molecular calcium-binding chaperone promoting folding, oligomeric assembly and quality control in the ER via the calreticulin/calnexin cycle (By similarity). This lectin may interact transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER (By similarity). Probably by controlling the folding of extracellular matrix protein unc-52/Perlecan, may play a role in the formation of fibrous organelles, a hemidesmosome-like structure attaching muscles to the epidermis. Protects dopaminergic neurons against oxidative stress-induced neurodegen [...]

DNaJ domain (Prokaryotic heat shock protein).

Thioredoxin; Belongs to the thioredoxin family.

GrpE protein homolog, mitochondrial; Essential component of the PAM complex, a complex required for the translocation of transit peptide-containing proteins from the inner membrane into the mitochondrial matrix in an ATP-dependent manner. Seems to control the nucleotide-dependent binding of mitochondrial HSP70 to substrate proteins (By similarity).
