Fraction of tumor cells in few cases of squamous cell carcinoma of head and neck, lung and skin displayed moderate to strong nuclear immunoreactivity. Several cases of melanoma showed moderate to strong membranous staining. Fraction of tumor cells in few cases of colorectal, breast, urothelial, prostate and cervical cancer displayed weak to moderate staining. Remaining cancer tissues were negative.
GENE INFORMATION
Gene name
PRDM1 (HGNC Symbol)
Synonyms
BLIMP1, PRDI-BF1
Description
PR domain containing 1, with ZNF domain (HGNC Symbol)
Entrez gene summary
This gene encodes a protein that acts as a repressor of beta-interferon gene expression. The protein binds specifically to the PRDI (positive regulatory domain I element) of the beta-IFN gene promoter. Transcription of this gene increases upon virus induction. Two alternatively spliced transcript variants that encode different isoforms have been reported. [provided by RefSeq, Jul 2008]
