Critical Reviews in Biochemistry and Molecular Biology, 1989
The nucleus, like all organelles, is composed of a unique set of proteins. This article discusses the possible mechanisms for localization of only certain proteins to the nucleus, transport of proteins across the nuclear envelope, and retention of proteins in the nuclear interior.

Publisher Summary This chapter discusses the process of nuclear protein transport. Work on the mechanism of nuclear transport has led to a fairly detailed understanding of how proteins are targeted for import or export. This work has changed the way in which researchers need to think about potential transport mechanisms for their own protein of ...

Protein kinase C (PKC) isozymes constitute a family of ubiquitous phosphotransferases which act as key transducers in many agonist-induced signaling cascades. To date, at least 11 different PKC isotypes have been identified and are believed to play distinct regulatory roles. PKC isoforms are physiologically activated by a number of lipid cofactors. PKC

Nuclear Protein Transport Pathways
Nephron Experimental Nephrology, 1999Nuclear proteins like transcription factors and ribosomal proteins are synthesized in the cytoplasm and have to be transported into the nucleus to fulfill their functions. The transport of proteins >20–60 kD through the nuclear pore complex (NPC) into the nucleus is an active, energy-requiring process.

Proteome analysis is becoming a powerful tool of discovery-driven research, with investigations ranging from whole organisms to specific subcellular compartments. Especially for the latter, efficient and robust methods for protein purification are the prerequisite for obtaining meaningful proteomic data.

Androgen-receptor-interacting nuclear proteins
Biochemical Society Transactions, 2000Androgen receptor (AR) belongs to the super-family of nuclear hormone receptors that employ complex molecular mechanisms to guide the development and physiological functions of their target tissues. Our recent work has led to the identification of four novel proteins that recognize AR zinc-finger region (ZFR) both in vivo and in vitro.

Protein synthesis in nuclear residual protein
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 19651. The incorporation of radioactive amino acids into the nuclear residual protein from calf thymus has been investigated in vitro. 2. The nuclear residue has been found to incorporate actively [14C]tryptophan into its protein. 3. Optimal incorporation of [14C]tryptophan was obtained in the presence of Mg2+, adenosine 5′-triphosphate and an ...

Publisher Summary The control of gene expression involves several steps at which specific sequences in pre-mRNA transcripts, as well as those in small RNA molecules, are recognized by proteins. RNA-binding proteins can be expected to mediate interactions in a variety of cellular processes, including those occurring in the transcription complex, the ...

Phosphorylation of nuclear proteins
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1983Many nuclear proteins are phosphorylated: they range from enzymes to several structural proteins such as histones, non-histone chromosomal proteins and the nuclear lamins. The pattern of phosphorylation varies through the cell cycle. Although histone H1 is phosphorylated during interphase its phosphorylation increases sharply during mitosis. Histone H3,

The nuclear envelope forms the boundary between the nucleus and the cytoplasm and as such regulates the exchange of macromolecules between the two compartments. The channels through the nuclear envelop that actually mediate this macromolecular traffic are the nuclear pore complexes.
