L'article est une revue generale concernant le transport, apres synthese cytoplasmique, des proteines nucleaires dans le noyau a travers la membrane nucleaire. Les techniques d'etude sont presentees (techniques in vivo sur cellules, in vitro sur noyaux artificiels ou noyaux naturels reconstitues, approche genetique).

Nuclear protein kinases include enzymes that transfer the gamma-phosphate of ATP to serine, threonine, lysine or histidine in proteins. Nuclear kinases with a preference for basic proteins are known as histone kinases; those preferring acidic protein substrates are casein kinases.

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 ...

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.

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.

Phosphorylation of nuclear proteins
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1983Abstract Many 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

NuMA, a nuclear protein involved in mitosis and nuclear reformation
Current Opinion in Cell Biology, 1994NuMA, a nuclear protein that associates with the mitotic apparatus, was identified in 1980 as a high molecular weight component of the nuclear matrix with the unusual property of associating with the microtubules of the spindle apparatus during mitosis.

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.
