25512553 the decrease in 5-HT uptake rates of GDM trophoblast is the consequence of defective insulin signaling, which entraps SERT with ERp44 and impairs its glycosylation.
25097228 Endogenous ERp44 is O-glycosylated and secreted by human primary endometrial cells, suggesting possible pathophysiological roles of these processes.
24804790 findings indicated that overexpression of miR-101 could downregulate ERp44
23979138 Data indicate that protein disulfide isomerase (PDI) and ERp44 dynamically localize Ero1alpha and peroxiredoxin 4 in early secretory compartment (ESC).
23685074 The ERp44 assembly control cycle couples secretion fidelity and efficiency downstream of the calnexin/calreticulin and BiP-dependent quality control cycles.
22451649 ERp44 together with Ero1-Lalpha plays an important role in disulfide formation of SERT, which may be a prerequisite step for the assembly of SERT molecules in oligomeric form.
22190034 HIV-1 gp120 is identified to have a physical interaction with endoplasmic reticulum protein 44 (ERP44) in human HEK293 and/or Jurkat cell lines by using affinity tagging and purification mass spectrometry analyses
20628086 Observational study of gene-disease association, gene-environment interaction, and pharmacogenomic / toxicogenomic. (HuGE Navigator)
19913121 Observational study of gene-disease association. (HuGE Navigator)
18552768 Crystal structure of ERp44 at a resolution of 2.6 A, is presented.
18508857 Study shows that SUMF1 interacts with protein disulfide isomerase (PDI) and ERp44, two thioredoxin family members residing in the early secretory pathway, and with ERGIC-53, a lectin that shuttles between the ER and the Golgi.
18178549 ERp44-mediated retention of FGE, indicating that noncovalent interactions between ERp44 and FGE are sufficient to mediate ER retention.
17805346 ERGIC-53 provides a platform that receives micro(2)L(2) subunits from the BiP-dependent checkpoint, assisting polymerization. In this process, ERp44 couples thiol-dependent assembly and quality control.
16677073 Ero1alpha and Ero1beta are retained in the endoplasmic reticulum by interactions with PDI and ERp44
11847130 contains a thioredoxin domain with a CRFS motif and is induced during ER stress
