Los autores, de la Darthmouth Medical School (Estados Unidos), explican que si no se une al cinc, la rodopsina se vuelve muy inestable, característica típica de la retinitis pigmentosa.
Los investigadores han identificado el lugar de la proteína que se une al cinc y consideran que algunos casos de la enfermedad ocular se producen por mutaciones en la rodopsina que impiden esa unión.

Retinitis Pigmentaria
Cinc y retinitis pigmentosa
Un artículo publicado en el "Journal of Biological Chemistry" muestra que el cinc desempeña un importante papel en la función normal de la rodopsina, una proteína del ojo implicada en la retinitis pigmentosa, enfermedad hereditaria que a menudo conduce a ceguera.
Los autores, de la Darthmouth Medical School (Estados Unidos), explican que si no se une al cinc, la rodopsina se vuelve muy inestable, característica típica de la retinitis pigmentosa.
Los investigadores han identificado el lugar de la proteína que se une al cinc y consideran que algunos casos de la enfermedad ocular se producen por mutaciones en la rodopsina que impiden esa unión.
