DNAJB12 and Hsp70 Mediate Triage of Misfolded Membrane Proteins for Proteasomal versus Lysosomal Degradation.
Article in Autophagy reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The endoplasmic reticulum (ER) fills the cell with a continuous network of sealed membrane tubules and sheets. The ER is subdivided into microdomains mediating one-third of total protein biosynthesis, oxidative protein folding, secretion, protein quality control, calcium signaling, marcoautophagy/autophagy, stress sensing, and apoptosis. Defects in ER-calcium homeostasis underlie several diseases. Damage to the ER by misfolded membrane proteins is suppressed by specific HSPA/Hsp70 and DNAJ/Hsp40 chaperone pairs that select intermediates for ubiquitination and ER-associated degradation (ERAD) via the proteasome. The ER-transmembrane Hsp40 chaperone DNAJB12 and HSPA/Hsp70 also target toxic intermediates of misfolded membrane proteins for ER-associated autophagy (ERAA). DNAJB12-HSPA/Hsp70 maintain membrane protein degradation intermediates in detergent-soluble and degradation-competent states. DNAJB12-HSPA/Hsp70 also interact with the autophagy initiation kinase ULK1 on ER tubules containing ERAD-resistant misfolded membrane proteins (ERAD-RMPs). Omegasomes are ER microdomains where the autophagosome precursor or phagophore (PG) forms. ER tubules loaded with ERAD-RMPs enter omegasomes where they are converted into ER-connected PG (ER-PG). The Atg8 (autophagy related 8)-family member GABARAP (GABA type A receptor-associated protein) facilitates transfer of ERAD-RMPs from ER-PGs to autolysosomes (AL) that dock transiently with omegasomes. This article describes a model for DNAJB12-HSPA/Hsp70 action during the conformation-dependent triage in the ER of misfolded membrane proteins for folding versus proteasomal or AL degradation.
