Cancer tissues showed weak to moderate nuclear staining. Few cases of squamous cell carcinomas of cervix showed strong positivity. Carcinoid and renal cancers were negative.
A single case of seminoma and a few cases of stomach cancer showed moderate nuclear immunoreactivity. Remaining cancer tissues were negative.
GENE INFORMATION
Gene name
RBBP6 (HGNC Symbol)
Synonyms
P2P-R, PACT, SNAMA
Description
Retinoblastoma binding protein 6 (HGNC Symbol)
Entrez gene summary
The retinoblastoma tumor suppressor (pRB) protein binds with many other proteins. In various human cancers, pRB suppresses cellular proliferation and is inactivated. Cell cycle-dependent phosphorylation regulates the activity of pRB. This gene encodes a protein which binds to underphosphorylated but not phosphorylated pRB. Multiple alternatively spliced transcript variants that encode different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
