|Reactivity||Human, Mouse, Rat|
|Calculated MW||149075 Da|
|Positive Control||3T3 cell lysate|
|Application & Usage||The antibody can be used for Western blot analysis (1-4 µg/ml). However, the optimal conditions should be determined individually. Blocking peptide is available separately.|
|Other Names||Par-3 (Partitioning defective 3) homolog|
|Formulation||100 µg (0.5 mg/ml) affinity purified rabbit anti-PARD3 polyclonal antibody in phosphate buffered saline (PBS), pH 7.2, containing 30% glycerol, 0.5% BSA, 5 mM EDTA and 0.01% thimerosal.|
|Handling||The antibody solution should be gently mixed before use.|
|Reconstitution & Storage||-20 °C|
|Precautions||PARD3 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||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. 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 (By similarity). Involved in Schwann cell peripheral myelination.|
|Cellular Location||Cytoplasm. Endomembrane system. Cell junction. Cell junction, tight junction. Cytoplasm, cell cortex Cytoplasm, cytoskeleton. Cell membrane Note=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. Presence of KRIT1, CDH5 and RAP1B is required for its localization to the cell junction (By similarity). Colocalized with SIRT2 in internode region of myelin sheat.|
|Tissue Location||All isoforms are expressed in heart, while expression in brain is mainly limited to isoform 1, and to isoform 3 to a weaker level|
