Removal of nonspecific binding proteins is required in co-immunoprecipitation with nuclear proteins
Whether protein samples should be pretreated to remove nonspecific binding proteins in co-immunoprecipitation (CO-IP) is controversial. In this work, nonspecific binding of proteins to agarose beads was found to be greater than that to magnetic beads ...

Protein sub-nuclear localization prediction using SVM and Pfam domain information. [PDF]
The nucleus is the largest and the highly organized organelle of eukaryotic cells. Within nucleus exist a number of pseudo-compartments, which are not separated by any membrane, yet each of them contains only a specific set of proteins.

The defining feature of eukaryotic organisms is the cell nucleus. All nuclear proteins are synthesized in the cytoplasm and need to be imported through the nuclear pore complexes (NPCs) into the nucleus. Import can be directed by various signals, of which the classical nuclear localization signal (NLS) and the M9 import signal are the best ...

Protein phosphatases at the nuclear envelope [PDF]
The nuclear envelope (NE) is a unique topological structure formed by lipid membranes (Inner and Outer Membrane: IM and OM) interrupted by open channels (Nuclear Pore complexes). Besides its well-established structural role in providing a physical separation between the genome and the cytoplasm and regulating the exchanges between the two cellular ...

Laminopathies: what can humans learn from fruit flies
Lamin proteins are type V intermediate filament proteins (IFs) located inside the cell nucleus. They are evolutionarily conserved and have similar domain organization and properties to cytoplasmic IFs. Lamins provide a skeletal network for chromatin, the

Targeting nuclear transporters in cancer: Diagnostic, prognostic and therapeutic potential [PDF]
The Karyopherin superfamily is a major class of soluble transport receptors consisting of both import and export proteins. The trafficking of proteins involved in transcription, cell signalling and cell cycle regulation among other functions across the ...

The function of the nuclear envelope in nuclear protein accumulation. [PDF]
The mechanism by which proteins accumulate in the cell nucleus is not yet known. Two alternative mechanisms are discussed here: (a) selective unidirectional entry of karyophilic proteins through the nuclear pores, and (b) free diffusion of all proteins through the nuclear pores and specific binding of nuclear proteins to nondiffusible components of the

Hutchinson-Gilford Progeria Syndrome—Current Status and Prospects for Gene Therapy Treatment
Hutchinson-Gilford progeria syndrome (HGPS) is one of the most severe disorders among laminopathies—a heterogeneous group of genetic diseases with a molecular background based on mutations in the LMNA gene and genes coding for interacting proteins.

Proteomic identification of heterogeneous nuclear ribonucleoprotein L as a novel component of SLM/Sam68 nuclear bodies [PDF]
Background: Active pre-mRNA splicing occurs co-transcriptionally, and takes place throughout the nucleoplasm of eukaryotic cells. Splicing decisions are controlled by networks of nuclear RNA-binding proteins and their target sequences, sometimes in ...
