[Molecular characteristics of RB1 tumor suppressor gene]
1Hospital Municipal de Oncología María Curie, Buenos Aires, Argentina.
Abstract:
RB1 tumor suppressor gene is implicated in the development of some malignancies, among which retinoblastoma is the most common; in this tumor RB1 gene is generally deleted. This gene is closely associated to the cell cycle regulation and it constitutes a molecular binding target of viral oncoproteins, which inhibits its protein product, thus interrupting cell cycle progression. This paper describes its molecular features, in order to identify its mutations.
Insights
