Na+/H+ exchanger type 1 is a receptor for pathogenic subgroup J avian leukosis virus.

ABSTRACT: Subgroup J avian leukosis virus (ALV-J) is a recently identified avian oncogenic retrovirus responsible for severe economic losses worldwide. In contrast with the other ALV subgroups, ALV-J predominantly induces myeloid leukosis in meat-type chickens. Despite significant homology with the other ALV subgroups across most of the genome, the envelope protein of ALV-J (EnvJ) shares low homology with the others. Pathogenicity and myeloid leukosis induction map to the env gene of ALV-J. A chimeric protein composed of the surface domain of EnvJ fused to the constant region of a rabbit IgG and mass spectrometry were used to identify the chicken Na(+)/H(+) exchanger type 1 (chNHE1) as a binding protein for ALV-J. Flow cytometry analysis and coprecipitation experiments demonstrated a specific intera
