Medical and Biotech [MESH] Definitions

Product of the retinoblastoma tumor suppressor gene. It is a nuclear phosphoprotein hypothesized to normally act as an inhibitor of cell proliferation. Rb protein is absent in retinoblastoma cell lines. It also has been shown to form complexes with the adenovirus E1A protein, the SV40 T antigen, and the human papilloma virus E7 protein.

A ubiquitously expressed regulatory protein that contains a retinoblastoma protein binding domain and an AT-rich interactive domain. The protein may play a role in recruiting HISTONE DEACETYLASES to the site of RETINOBLASTOMA PROTEIN-containing transcriptional repressor complexes.

A malignant tumor arising from the nuclear layer of the retina that is the most common primary tumor of the eye in children. The tumor tends to occur in early childhood or infancy and may be present at birth. The majority are sporadic, but the condition may be transmitted as an autosomal dominant trait. Histologic features include dense cellularity, small round polygonal cells, and areas of calcification and necrosis. An abnormal pupil reflex (leukokoria); NYSTAGMUS, PATHOLOGIC; STRABISMUS; and visual loss represent common clinical characteristics of this condition. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2104)

A retinoblastoma-binding protein that is involved in CHROMATIN REMODELING, histone deacetylation, and transcription repression. Although initially discovered as a retinoblastoma binding protein it has an affinity for core HISTONES and is a subunit of chromatin assembly factor-1 where it plays a role in the deposition of NUCLEOSOMES on newly synthesized DNA.

A retinoblastoma-binding protein that is found as a subunit of protein complexes involved in the acetylation of newly synthesized histones. Although initially discovered as a retinoblastoma binding protein, it also has an affinity for core HISTONES and plays a role in recruiting core histone proteins to the active site of the acetyltransferase enzyme complexes.
