  • 功能Adapter protein involved in asymmetrical cell division and cell polarization processes. Seems to play a central role in the formation of epithelial tight junctions. Targets the phosphatase PTEN to cell junctions (By similarity). Association with PARD6B may prevent the interaction of PARD3 with F11R/JAM1, thereby preventing tight junction assembly. The PARD6-PARD3 complex links GTP-bound Rho small GTPases to atypical protein kinase C proteins. Required for establishment of neuronal polarity and normal axon formation in cultured hippocampal neurons.
  • 组织特异性Widely expressed.
  • 序列相似性Belongs to the PAR3 family.
    Contains 3 PDZ (DHR) domains.
  • 结构域Contains a conserved N-terminal oligomerization domain (NTD) that is involved in oligomerization and is essential for proper subapical membrane localization.
    The second PDZ domain mediates interaction with membranes containing phosphoinositol lipids.
  • 翻译后修饰Phosphorylated by PRKCZ. EGF-induced Tyr-1127 phosphorylation mediates dissociation from LIMK2.
    Phosphorylation by STK6/AURKA at Ser-962 is required for the normal establishment of neuronal polarity.
  • 细胞定位Endomembrane system. Cell junction. Cell junction > tight junction. Cell membrane. Cytoplasm > cell cortex. Cytoplasm > cytoskeleton. Localized along the cell-cell contact region. Colocalizes with PARD6A and PRKCI at epithelial tight junctions. Colocalizes with the cortical actin that overlays the meiotic spindle during metaphase I and metaphase II (By similarity). Presence of KRIT1, CDH5 and RAP1B is required for its localization to the cell junction.

Anti-PARD3 antibody 图像

  • ab64646 stained A549 cells. The cells were 100% methanol fixed for 5 minutes at-20°C* and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1hour at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab64646 at 5µg/ml) overnight at +4°C. The secondary antibody (pseudo-colored green) was Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) used at a 1/1000 dilution for 1hour at room temperature. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1hour at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

  • IHC image of PARD3 staining in Human lung adenocarcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab64646, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
