Nuclear protein tyrosine kinases

Trends in Biochemical Sciences, 1994
Protein tyrosine phosphorylation plays an important role in the transduction of extracellular signals. The prototypical protein tyrosine kinases are localized at the plasma membrane and are coupled to receptors that bind extracellular factors. Thus, protein tyrosine phosphorylation was previously thought to occur only in the cytoplasm. However, several

Nuclear proteins in spermatogenesis

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1986
Mammalian 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, 2001
The 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 export of proteins: The role of nuclear retention

Cell, 1993
Proteins that shuttle between nucleus and cytoplasm are implicated in transport and signal transduction processes. Using assays based on interspecies heterokaryons and microinjection of Xenopus oocytes, we examined what structural features determine nuclear export of shuttling proteins.

Mechanisms of nuclear protein import

Current Opinion in Cell Biology, 1995
The past two years have seen a significant increase in our understanding of nuclear protein import. Five cytosolic import factors have been identified, two of which have been shown to directly interact with components of the nuclear pore complex. These findings enable refinement of previous models for steps in the nuclear import pathway, and provide a ...

Nuclear basic proteins in spermiogenesis

Biochimie, 1998
In animal species, spermiogenesis, the late stage of spermatogenesis, is characterized by a dramatic remodelling of chromatin which involves morphological changes and various modifications in the nature of the nuclear basic proteins. According to the evolution of species, three situations can be observed: a) persistence of somatic histones or ...

Nuclear Protein Import

2007
Entry into the eukaryotic cell nucleus occurs through multiple pathways involving specific targeting signals, and intracellular receptor molecules of the importin/karyopherin superfamily which recognise and dock the nuclear import substrates carrying these signals at the nuclear pore.
