title: Human autoimmune serum antibodies against gag gene p30 retroviral protein also react with a U1-SnRNP 68K comigrant protein.
abstract: Using Immunoblotting procedure, we showed that autoimmune human antibodies reacting with mouse retrovirus gag-p30 also reacted with a HnRNP 68 Kd protein. Since U1-SnRNP 68 K and p30-gag proteins show 40% homology, the detected 68 Kd protein is likely to be the U1-RNA 68 K.
