What's a GeneRIF?

The results suggest that PDI flexibility enables it to interact with many different partner molecules of widely different sizes and shapes.
Title: The flexibility and dynamics of protein disulfide isomerase.
Data show that binding of mannosidase Htm1 to protein disulfide isomerase Pdi1 is required for endoplasmic reticulum (ER)-associated protein degradation (ERAD).
Title: A Complex of Htm1 and the Oxidoreductase Pdi1 Accelerates Degradation of Misfolded Glycoproteins.
ERO1 is enzymatically active even with its regulatory disulfides intact, and further activation of ERO1 by reduction of the regulatory disulfides requires the reduction of non-catalytic Cys(90)-Cys(97)disulfide in PDI1.

NP_009887.1

EC 5.3.4.1

Protein disulfide isomerase; multifunctional oxidoreductase of the ER lumen, essential for disulfide bond formation in secretory and cell-surface proteins, processing of non-native disulfide bonds; Ero1p activator; complexes with exomannosidase, Mnl1p to facilitate the recognition of misfolded glycoproteins and the trimming of glycan Man8GlcNAc2 to Man7GlcNAc2 on substrates, thereby accelerating ERAD; PDI1 has a paralog, EUG1, that arose from the whole genome duplication
