What the tool is doing

PDIA6 is described as an ER-resident disulfide isomerase and molecular chaperone. In this paper it undergoes Ca2+-triggered condensation and recruits proinsulin.

Source 2DOI PubMed

Resources required

Its reported function here depends on the ER environment and Ca2+-triggered condensation behavior.

Source 2DOI PubMed

What problem it solves

The abstract links PDIA6 to improved oxidative folding of proinsulin and reduced aggregation.

Source 2DOI PubMed

What it does not solve

The abstract does not establish PDIA6 as a standalone engineered reagent or define its broader applicability outside this biological setting.

Source 2DOI PubMed

Alternatives

The abstract does not name alternative chaperones or isomerases within this paper's own evidence.

Source 2DOI PubMed

Evidence Snippets

Here we report the discovery of a multichaperone condensate in the ER lumen, which is formed around the chaperone PDIA6 during protein folding homeostasis.

Claim 3functional effectsupports2025Source 2DOI PubMed

PDIA6 condensates recruit proinsulin and accelerate oxidative proinsulin folding while suppressing proinsulin aggregation.

Quoted textsource-backed

We further show that the PDIA6 condensates recruit proinsulin, thereby accelerating the oxidative proinsulin folding and suppressing the proinsulin aggregation inside quality control granules

Ca2+ triggers condensation of PDIA6 into ER quality control granules.

Quoted textsource-backed

Here we show that Ca2+ triggers the condensation of PDIA6, an ER-resident disulfide isomerase and molecular chaperone, into quality control granules.

Claim 5mechanismsupports2025Source 1DOI PubMed

PDIA6 condensates form in a Ca2+-dependent manner.

Claim 6mechanismsupports2025Source 2DOI PubMed

PDIA6 condensation is mediated by transient but specific electrostatic interactions between the first and third folded thioredoxin-like domains of PDIA6 rather than by a low-complexity-domain condensation mechanism.

Quoted textsource-backed

In contrast to the condensation mechanism observed for proteins containing low-complexity domains, our results indicate that transient but specific electrostatic interactions occur between the first and the third folded thioredoxin-like domains of PDIA6.
