Descriptor English: Host Factor 1 Protein
Descriptor Spanish: Proteína de Factor 1 del Huésped
Descriptor proteína 1 del factor huésped
Scope note: Factor de integración del huésped identificado originalmente como proteína bacteriana requerida para la integración del bacteriófago Q beta (ALLOLEVIVIRUS). Su función celular puede ser regular la estabilidad y procesamiento del ARN mensajero por unirse fuertemente a poli ARN (A) e interferir en la unión de ribosomas.
