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 proteins in spermatogenesis
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1986Mammalian somatic type histone variants are replaced or supplemented in early primary spermatocytes and possibly spermatogonia by testis specific and testis enriched histone variants. The testis complement of histones is replaced entirely by transition basic proteins in mid-spermatids.

Inner nuclear membrane proteins and the nuclear lamina
Journal of Cell Science, 2001The nuclear lamina is a scaffolding structure at the nuclear periphery and is required for maintenance of nuclear shape, spacing of nuclear pore complexes, organization of heterochromatin, DNA replication, and regulation of transcription factors.

Nuclear envelope proteins and their role in nuclear positioning and replication
Biochemical Society Transactions, 2010Controlled movement of the nucleus is important in a wide variety of plant cellular events. Positioning involving intact nuclei occurs in cell division, development, tip growing systems such as the root hair and in response to stimuli, including light, touch and infection.

Extraction of Nuclear Proteins
2006The integrity of a subcellular proteome such as the nucleus, is largely dependent on purification of the isolated compartment away from other cellular contaminants. The separation of high-purity nuclei from plants is a difficult task. However, successful purification has been achieved through a series of fractionation processes.

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 ...

Characterization of a Sperm Nuclear Protein
American Journal of Reproductive Immunology, 1996PROBLEM: The molecular identity of sperm DNA‐binding structural proteins contributing to the integrity of a sperm residual high salt/nuclease resistant nuclear structure is studied by cDNA cloning and monoclonal antibodies to the recombinant polypeptide.

An inhibitor protein of nuclear protein kinases
Nature, 1979THE cyclical phosphorylation and dephosphorylation of proteins, catalysed by protein kinases and phosphoprotein phosphatases, respectively, are important ways in which cells regulate many of their metabolic activities. Cells seem to have at least two distinct phosphorylation systems, one in the cytoplasm, the other in the nucleus.
