Application Notes
This PDZK1 antibody is useful for Immunohistochemistry paraffin embedded sections, Immunocytochemistry/Immunofluorescence and Western blot. In Western blot a single band is observed at ~70 kDa. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended.In Simple Western only 10-15 uL of the recommended dilution is used per data point.

The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Theoretical MW

Scaffold or adaptor proteins recruits and/or anchor their binding partners to specific subcellular locations, serving as a platform to regulate interactions between proteins involved in diverse signal transduction pathways, and PDZK1 (PDZ domain-containing protein 1) is a scaffold protein belonging to NHERFs family. PDZK1 expression is largely limited to epithelial cells and is mainly expressed in renal proximal epithelial cells, hepatocytes, and at a lower level in other epithelial as well as certain endothelial cells. PDZK1 has four PDZ domains which facilitates its interaction with its binding partners, including ion transporters (e.g. CFTR, OCTN1/OCTN2 etc) and several GPCRs (e.g. HTR2B, SSTR family members). Through its interaction with HDL and SR-BI, PDZK1 can play role in reverse cholesterol transport and for HDL-mediated vascular re-endothelialisation. When complex with SLC9A3R1, PDZK1 cluster proteins that are functionally dependent in a mutual fashion and modulate the trafficking as well as the activity of associated membrane proteins. PDZK1 plays a role in cellular mechanisms associated with multidrug resistance through its interaction with ABCC2 and PDZK1IP1. PDZK1 also implicates in connecting SCARB1 with cellular machineries for intracellular cholesterol transport and/or metabolism and regulation of proximal tubular Na+-dependent inorganic phosphate cotransport.
