Members of the heterogeneous nuclear ribonucleoprotein (hnRNP) H protein family, H, H′,
F, and 2H9, are involved in pre-mRNA processing. We analyzed the assembly of these …

In yeast, four factors (CF I, CF II, PF I, and PAP) are required for accurate pre-mRNA
cleavage and polyadenylation in vitro. CF I can be separated further into CF IA and CF IB …

The transcription factor Pho4 is phosphorylated and localized predominantly to the
cytoplasm when budding yeast are grown in phosphate-rich medium and is …

The constitutive transport elements (CTEs) of type D retroviruses are cis‐acting elements
that promote nuclear export of incompletely spliced mRNAs. Unlike the Rev response …

The unique N-terminal region of the parvovirus VP1 capsid protein is required for infectivity
by the capsids but is not required for capsid assembly. The VP1 N terminus contains a …

Background: Mig1 is a transcriptional repressor responsible for glucose repression of many
genes in the budding yeast Saccharomyces cerevisiae. Glucose regulates Mig1 function by …

The Drosophila PBC protein Extradenticle (Exd) is regulated at the level of its subcellular
distribution: It is cytoplasmic in the absence of Homothorax (Hth), a Meis family member, and …

Heterogeneous nuclear ribonucleoproteins (hnRNPs) are involved in several RNA-related
biological processes such as transcription, pre-mRNA processing, mature mRNA transport …

Cytoplasmic localization of mRNA molecules is a powerful mechanism for generating cell
polarity. In vertebrates, one paradigm is localization of Vg1 RNA within the Xenopus oocyte …

Tomato heat stress transcription factor HsfA2 is a shuttling protein with dominant cytoplasmic
localization as a result of a nuclear import combined with an efficient export. Besides the …
