Most malignant cells showed weak to moderate nuclear and occasional cytoplasmic staining. A few cases of malignant gliomas, melanomas, stomach and pancreatic cancers displayed strong positivity. Most malignant lymphomas as well as several malignant gliomas, prostate, endometrial, urothelial, gastric and liver cancers were negative.
GENE INFORMATION
Gene name
COPS6 (HGNC Symbol)
Synonyms
CSN6, MOV34-34KD
Description
COP9 signalosome subunit 6 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is one of the eight subunits of COP9 signalosome, a highly conserved protein complex that functions as an important regulator in multiple signaling pathways. The structure and function of COP9 signalosome is similar to that of the 19S regulatory particle of 26S proteasome. COP9 signalosome has been shown to interact with SCF-type E3 ubiquitin ligases and act as a positive regulator of E3 ubiquitin ligases. This protein belongs to translation initiation factor 3 (eIF3) superfamily. It is involved in the regulation of cell cycle and likely to be a cellular cofactor for HIV-1 accessory gene product Vpr.
