Cancer tissues showed moderate nuclear staining. Few cases of melanomas, testis, urothelial and cervical cancers showed strong nuclear positivity. Few cases of hepatocellular carcinomas were weakly stained or negative.
GENE INFORMATION
Gene name
RAD23A (HGNC Symbol)
Synonyms
HHR23A, MGC111083
Description
RAD23 homolog A, nucleotide excision repair protein (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is one of two human homologs of Saccharomyces cerevisiae Rad23, a protein involved in nucleotide excision repair. Proteins in this family have a modular domain structure consisting of an ubiquitin-like domain (UbL), ubiquitin-associated domain 1 (UbA1), XPC-binding domain and UbA2. The protein encoded by this gene plays an important role in nucleotide excision repair and also in delivery of polyubiquitinated proteins to the proteasome. Alternative splicing results in multiple transcript variants encoding multiple isoforms. [provided by RefSeq, Jun 2012]
