We have assessed whether antigenic proteins associated with small nuclear ribonucleoprotein particles (snRNP) are associated with the nuclear matrix. Immunofluorescence studies showed that a subset of these particles (those reactive with anti-Sm antisera) were associated with the nuclear matrix, while a different set of particles (those reactive with anti-La antisera) were not associated with the nuclear matrix. Immunoprecipitation experiments showed that three specific polypeptide components of the snRNP reactive with the anti-Sm antisera were significantly enriched in nuclear matrix proteins.
