  • 蛋白标签：
    N-terminal 6xHis-SUMO-tagged
  • 产品提供形式：
    Liquid or Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 缓冲液：
    Tris-based buffer,50% glycerol
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

  • 功能：
    Mediates thiol-dependent retention in the early secretory pathway, forming mixed disulfides with substrate proteins through its conserved CRFS motif. Inhibits the calcium channel activity of ITPR1. May have a role in the control of oxidative protein folding in the endoplasmic reticulum. Required to retain ERO1A and ERO1B in the endoplasmic reticulum.
  • 基因功能参考文献：
    1. Endogenous ERp44 is O-glycosylated and secreted by human primary endometrial cells, suggesting possible pathophysiological roles of these processes. PMID: 25097228
    2. findings indicated that overexpression of miR-101 could downregulate ERp44 PMID: 24804790
    3. 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. PMID: 25512553
    4. The ERp44 assembly control cycle couples secretion fidelity and efficiency downstream of the calnexin/calreticulin and BiP-dependent quality control cycles. PMID: 23685074
    5. 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. PMID: 22451649
    6. contains a thioredoxin domain with a CRFS motif and is induced during ER stress PMID: 11847130
    7. Ero1alpha and Ero1beta are retained in the endoplasmic reticulum by interactions with PDI and ERp44 PMID: 16677073
    8. 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. PMID: 17805346
    9. ERp44-mediated retention of FGE, indicating that noncovalent interactions between ERp44 and FGE are sufficient to mediate ER retention. PMID: 18178549
    10. 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. PMID: 18508857
    11. Crystal structure of ERp44 at a resolution of 2.6 A, is presented. PMID: 18552768
