Most malignancies were negative or showed faint cytoplasmic positivity. Strong staining was found in a few renal cancers and hepatocellular carcinomas.
Malignant cells displayed weak to moderate cytoplasmic staining. Endothelial cells showed distinct positivity, especially in glioma.
GENE INFORMATION
Gene name
PDZK1 (HGNC Symbol)
Synonyms
NHERF3, PDZD1
Description
PDZ domain containing 1 (HGNC Symbol)
Entrez gene summary
This gene encodes a PDZ domain-containing scaffolding protein. PDZ domain-containing molecules bind to and mediate the subcellular localization of target proteins. The encoded protein mediates the localization of cell surface proteins and plays a critical role in cholesterol metabolism by regulating the HDL receptor, scavenger receptor class B type 1. Single nucleotide polymorphisms in this gene may be associated with metabolic syndrome, and overexpression of this gene may play a role in drug resistance of multiple myeloma. Pseudogenes of this gene are located on the long arm of chromosome 1. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
