title: The La antigen shuttles between the nucleus and the cytoplasm in CV-1 cells.
abstract: Recently we established a monoclonal antibody against the La-protein (Bachmann et al., Proc. Natl. Acad. Sci. USA, 83, 7770, 1986). The antibody gives a nuclear speckled type staining and, in addition, a perinuclear cytoplasmic staining on cultured cells in immunofluorescence microscopy. After inhibition of RNA synthesis the La-protein is transported into the cytoplasm. After prolonged inhibition it returns into the nucleus forming large growing speckles. The transport into the nucleus apparently depends on glycosylation.
