Malignant gliomas and testicular cancers showed strong nuclear positivity. Moderate nuclear staining with additional weaker cytoplasmic immunoreactivity was observed in breast and prostate cancers as well as several cases of malignant lymphomas, melanomas, urothelial, skin and liver cancers. Remaining malignant cells were weakly stained or negative.
GENE INFORMATION
Gene name
PHC1 (HGNC Symbol)
Synonyms
EDR1, HPH1, RAE28
Description
Polyhomeotic homolog 1 (Drosophila) (HGNC Symbol)
Entrez gene summary
This gene is a homolog of the Drosophila polyhomeotic gene, which is a member of the Polycomb group of genes. The gene product is a component of a multimeric protein complex that contains EDR2 and the vertebrate Polycomb protein BMH1. The gene product, the EDR2 protein, and the Drosophila polyhomeotic protein share 2 highly conserved domains, named homology domains I and II. These domains are involved in protein-protein interactions and may mediate heterodimerization of the protein encoded by this gene and the EDR2 protein. [provided by RefSeq, Jul 2008]
