Entry term(s) fosfoproteína nuclear del retinoblastoma p105-Rb
proteína Rb
proteína p105-Rb
Scope note: Producto del gen supresor del tumor retinoblastoma. Es una fosfoproteína nuclear que supuestamente actúa normalmente como inhibidor de la proliferación celular. La proteína Rb está ausente en las líneas celulares del retinoblastoma. También se ha demostrado que forma complejos con la proteína E1A del adenovirus, el antígeno SV40 T y la proteína E7 del virus del papiloma humano.

Scope note: 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.
