Gene Information
human ... RB1(5925)
General description
The gene encoding retinoblastoma-associated protein (RB1) is a tumor suppressor gene localized on human chromosome 13q14.2.
Biochem/physiol Actions
pRB, the product of retinoblastoma susceptibility gene RB-1, is one of the best-studied tumor suppressor gene products. At least two other pRB-related proteins, p107 and p130, have been identified and characterized. Mutations in RB-1 gene are often associated with the occurrence of various tumors. The activity of pRB is regulated through phosphorylation in a cell cycle-dependent manner. The hyperphosphorylated RB protein usually associates with the cell nucleus and binds transcription factors of the E2F family. pRB represses transcription of its target genes, such as cdc2, cyclin A, and oncogene c-Myc, c-Fos through the binding with E2F factors and thereby regulating cell proliferation.

Recent evidence indicates the existence of a genetic locus in chromosome region 13q14 that confers susceptibility to retinoblastoma, a cancer of the eye in children. A gene encoding a messenger RNA (mRNA) of 4.6 kilobases (kb), located in the proximity

The genomes of various tumour cells contain mutant oncogenes that act dominantly, in that their effects can be observed when they are introduced into non-malignant cells. There is evidence for another class of oncogenes, in which tumour-predisposing mutations are recessive

The retinoblastoma-predisposition gene, RB1, segregates as an autosomal dominant trait with high (90%) penetrance. Certain families, however, show an unusual low-penetrance phenotype with many individuals being unaffected, unilaterally affected, or with evidence of spontaneously regressed tumors. We have used single-strand

Although RNA aptamers can show comparable or better specificity and affinity to antibodies and have the advantage of being able to access different live cell compartments, they are often much less stable in vivo. We report here the first aptamer
