Taxonomic lineageEukaryotaFungiDikaryaAscomycotaSaccharomycotinaSaccharomycetesSaccharomycetalesSaccharomycetaceaeSaccharomyces

Protein attributes

Sequence length277 AA.
Sequence statusComplete.
Sequence processingThe displayed sequence is further processed into a mature form.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Non essential disulfide isomerase, which participates in the folding of proteins containing disulfide bonds. May be involved in glycosylation, prolyl hydroxylation and triglyceride transfer. Able to fold proteins by being directly oxidized by ERO1. Ref.1

Catalytic activity

Catalyzes the rearrangement of -S-S- bonds in proteins.

Subcellular location

Endoplasmic reticulum Ref.6.

Miscellaneous

Present with 1520 molecules/cell in log phase SD medium. Ref.7

Sequence similarities

Belongs to the protein disulfide isomerase family.

Contains 1 thioredoxin domain.
