From sites of transcription in the nucleus to the outreaches of the cytoplasm, messenger
RNAs are associated with RNA-binding proteins. These proteins influence pre-mRNA …

Active transport between the nucleus and cytoplasm involves primarily three classes of
macromolecules: substrates, adaptors, and receptors. Some transport substrates bind …

The SR proteins constitute a large family of nuclear phosphoproteins required for
constitutive pre-mRNA splicing. These factors also have global, concentration-dependent …

The SR proteins, a group of abundant arginine/serine (RS)-rich proteins, are essential pre-
mRNA splicing factors that are localized in the nucleus. The RS domain of these proteins …

Following transcription and processing, eukaryotic mRNAs are exported from the nucleus to
the cytoplasm for translation. Here we present evidence that mRNAs are targeted for nuclear …

The nuclear matrix antigen recognized by the monoclonal antibody (mAb) B1C8 is a novel
serine (S) and arginine (R)-rich protein associated with splicing complexes and is named …

The pathways of synthesis and maturation of pre‐messenger RNA in the nucleus have a
direct effect on the translational efficiency of mRNA in the cytoplasm. The transcription of …

Mammalian SR proteins are currently thought to function in mRNA export as well as splicing.
They contain multiple phosphorylated serine/arginine (RS/SR) dipeptides. Although SR …

Our understanding of protein export from the nucleus to the cytoplasm has been advanced
recently by the discovery of active, signal-mediated export pathways. Nuclear export signals …

In the salivary glands of the dipteran Chironomus tentans, a specific messenger
ribonucleoprotein (mRNP) particle, the Balbiani ring (BR) granule, can be visualized during …
