靶标

  • 功能Component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is required for several steps in the initiation of protein synthesis. The eIF-3 complex associates with the 40S ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-2:GTP:methionyl-tRNAi and eIF-5 to form the 43S preinitiation complex (43S PIC). The eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA for AUG recognition. The eIF-3 complex is also required for disassembly and recycling of post-termination ribosomal complexes and subsequently prevents premature joining of the 40S and 60S ribosomal subunits prior to initiation.
  • 序列相似性Belongs to the eIF-3 subunit B family.
    Contains 1 RRM (RNA recognition motif) domain.
    Contains 5 WD repeats.
  • 结构域The RRM domain mediates interaction with EIF3J.
  • 翻译后修饰Phosphorylated. Phosphorylation is enhanced upon serum stimulation.
  • 细胞定位Cytoplasm.

Anti-eIF3B antibody 图像

  • ICC/IF image of ab40799 stained MCF7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab40799, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    Performed under reducing conditions.

    Predicted band size : 92 kDa
    Observed band size : 110 kDa (why is the actual band size different from the predicted?)
    This antibody was raised against an immunogen that is predicted to cross react with both isoforms 1 and 2 of eIF3B. We believe that the band observed is isoform 2 due to its higher molecular weight of 110 kDa. Predicted molecular weights of the isoforms are 92 kDa and 99 kDa respectively.
