Cancer tissues showed moderate to strong granular cytoplasmic staining with additional nuclear staining in several cases. Several basal cell carcinomas were weakly stained.
This gene encodes a member of the protease subunit S10 family. The encoded protein is a subunit of the 26S proteasome which colocalizes with DNA damage foci and is involved in the ATP-dependent degradation of ubiquinated proteins. Alternative splicing results in multiple transcript variants [provided by RefSeq, Nov 2012]
