Nucleolina - Wikiwand

La nucleolina, una fosfoproteína nucleolar eucariótica, está implicada en la síntesis y maduración de los ribosomas. Se localiza principalmente en regiones fibrilares densas del nucleolo. El gen de la nucleolina humana consta de 14 exones y 13 intrones, extendiéndose a lo largo de aproximadamente 11.000 pares de bases. El intrón 11 del gen NCL codifica un ARN pequeño nucleolar, denominado U20.^[3]
