PARD3/Par3 in HEK293 Human Cell Line. PARD3/Par3 was detected in immersion fixed HEK293 human embryonic kidney cell line using Mouse Anti-Human PARD3/Par3 Monoclonal Antibody (Catalog # MAB8030) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to plasma membrane. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: PARD3/Par3

PARD3 (partitioning defective 3 homolog), also called Par3, is a widely expressed adapter protein involved in asymmetrical cell division, cell polarization, and tight junction formation. It forms a cell polarity complex with Par6 and aPKC (atypical protein kinase C), linking to PTEN (phosphatase and tensin homolog) in polarized epithelia and VE-Cadherin in polarized endothelia. The region used as an immunogen, human PARD3 amino acids (aa) 451-555 (of 1356 aa in full-length PARD3) shares 97% and 96% aa sequence identity with mouse and rat PARD3, respectively. It includes the second of three PDZ domains, a region which is involved in heterophilic interactions and is present within all 10 reported PARD3 isoforms that vary in length from 988 aa to 1356 aa.
