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.
Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Target Background

Non-catalytic component of the methylosome complex, composed of PRMT5, WDR77 and CLNS1A, which modifies specific arginines to dimethylarginines in several spliceosomal Sm proteins and histones. This modification targets Sm proteins to the survival of motor neurons (SMN) complex for assembly into small nuclear ribonucleoprotein core particles. Might play a role in transcription regulation. The methylosome complex also methylates the Piwi proteins (PIWIL1, PIWIL2 and PIWIL4), methylation of Piwi proteins being required for the interaction with Tudor domain-containing proteins and subsequent localization to the meiotic nuage.

  1. A 3.7 A structure of PRMT5, solved in complex with regulatory binding subunit MEP50 (methylosome associated protein 50, WDR77, p44), by single particle (SP) cryo-Electron Microscopy (cryo-EM) using micrographs of particles that are visibly crowded and aggregated. The catalytic PRMT5 subunits form a core tetramer and the MEP50 subunits are arranged peripherally in complex with the PRMT5 N-terminal domain. PMID: 29518110
  2. Data indicate that ZNF326 is an interaction partner and substrate of the PRMT5/WDR77 complex. PMID: 28977470
  3. In an in vitro assay of vascular smooth muscle cells, circRNA WDR77 silencing significantly inhibited cell proliferation and migration. Bioinformatics methods revealed that miR-124 and fibroblast growth factor 2 (FGF-2) were downstream targets of circRNA WDR77. PMID: 29042195
  4. SFN treatment of tumors results in reduced MEP50 level and H4R3me2s formation, confirming that that SFN impacts this complex in vivo. These studies suggest that the PRMT5/MEP50 is required for tumor growth and that reduced expression of this complex is a part of the mechanism of SFN suppression of tumor formation. PMID: 28854561
  5. Results provide evidence that PRMT5 and p44 regulate gene expression of growth and anti-growth factors to promote lung tumorigenesis. PMID: 27480244

  13. structure of the surprising hetero-octameric complex reveals the close interaction between the seven-bladed beta-propeller MEP50 and the N-terminal domain of PRMT5, and delineates the structural elements of substrate recognition. PMID: 23071334
  14. p44 plays a role in mediating the effects of hormones during ovarian tumorigenesis. PMID: 22022581
