PDZK1IP1 (PDZK1 interacting protein 1) is a non-glycosylated membrane protein, which resides in the plasma membrane and Golgi bodies. It has a hydrophobic N-terminal of 13 residues, making the PDZ-binding domain, and two transmembrane regions. The molecular weight of this protein is 17kDa, and is expressed significantly only in normal kidney, in the proximal tubular epithelial cells.
Synonyms: Anti-17 kDa membrane-associated protein; Anti-PDZK1-interacting protein 1; Anti-Protein DD96
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: PDZK1IP1 (PDZK1 interacting protein 1) acts as an anchor for PDZK1 (PDZ domain containing 1) protein, and in renal proximal tubules interacts with NaPi-IIa/PDZK1 comlex. In human cancer cells, it facilitates the Na-dependent transport of mannose and glucose, by interacting with SGLT transporters. Amplification of mRNA leads to its elevated levels in multiple human tumors, and this relates with tumor progression, as seen in breast, ovarian and prostate cancer. Overexpression of this gene in tumors is associated with good prognosis. This protein induces PI3K/AKT pathway, which leads to prevention of Myc-induced apoptosis. Its PDZ-binding domain is responsible for its capacity to increase reactive oxygen species (ROS), which in turn is implicated in tumorigenesis.
