El ARF GTPasa 1 (factor 1 de ribosilación de ADP) es una proteína que en los humanos está codificada por el gen ARF1.

Función

El factor de ribosilación de ADP 1 (ARF1) es un miembro de la familia de GTPasas ARF humanos. Los miembros de la familia codifican pequeñas proteínas de unión a nucleótidos de guanina que estimulan la actividad ADP-ribosiltransferasa de la toxina del cólera y desempeñan un papel en el tráfico vesicular como activadores de la fosfolipasa D. Los productos genéticos, incluidas 6 proteínas ARF y 11 proteínas similares a ARF, constituyen una familia de la superfamilia RAS. Las proteínas ARF se clasifican en clase I (ARF1, ARF2 y ARF3), clase II (ARF4 y ARF5) y clase III (ARF6), y los miembros de cada clase comparten una organización genética común. La proteína ARF1 está localizada en el aparato de Golgi y tiene un papel central en el transporte intra-Golgi. Para este gen se han encontrado múltiples variantes de transcripción empalmadas alternativamente que codifican la misma proteína.

El principal mecanismo de acción de Brefeldin A es mediante la inhibición de ARF1.
