The reason for the reported histone chaperone function of AtFKBP53 could perhaps, be attributed to this nucleoplasmin fold. Nucleoplasmins form a significant class of histone chaperones, defined by a representative N-terminal pentameric core domain having doughnut architecture with a central pore and an unstructured C-terminal domain. Control Systems - Stability Analysis - TutorialspointStep 3 Verify the sufficient condition for the Routh-Hurwitz stability.. There are two sign changes in the first column of Routh table. Hence, the control system is unstable. In the Routh-Hurwitz stability criterion, we can know whether the closed loop poles are in on left half of the s plane or on the right half of the s plane or on an imaginary axis. Histone hyperacetylation:its effects on nucleosome May 01, 2002 · Analysis of the stability and function of nucleoplasmin through cysteine mutants. Archives of Biochemistry and Biophysics 2005 , 437 (2) , 205-214. DOI:10.1016 analysis of the stability and function of nucleoplasminj.abb.2005.03.011.
eed as a single polypeptide in nucleoplasmin-like FKBP (NPL-FKBP) histone chaperones. Saccharomyces cerevisiae has two NPL-FKBPs:Fpr3 and Fpr4. These paralogs are 72% similar and are clearly derived from a common ancestral gene. This suggests that they may have redundant functions. Mutation of cysteine 21 inhibits nucleophosmin analysis of the stability and function of nucleoplasminB23 It is thought to function as a nucleosome chaperone by binding to histones [14,15]. The N-terminus of NPM analysis of the stability and function of nucleoplasminB23 shows extensive homology to the nucleoplasmin family of acidic histone chaperones . Nucleoplasmin and NPM analysis of the stability and function of nucleoplasminB23 have both been shown to form oligomers, which are required for histone binding and assembly .

User-added text is available under Proteopedia:Terms of Service and the Nucleoplasmin - Xenopus laevis (African clawed frog)Acts as a chaperone for histones, such as histone H2A-H2B, and thus regulates the assembly of nucleosome cores (PubMed:11684019, PubMed:19055325). Involved in chromatin remodeling, especially during fertilization and early embryonic development (By similarity). May be involved in sperm chromatin decondensation during fertilization (PubMed:17510054).
NPM1 is a ubiquitously eed nucleolar protein that shuttles between the nucleus and cytoplasm. It is implicated in multiple functions, including ribosomal protein assembly and transport, control of centrosome duplication, and regulation of the tumor suppressor ARF ().NPM1 mutations that relocalize NPM1 from the nucleus into the cytoplasm are associated with development of acute myeloid RCSB PDB - 2VTX:ACTIVATION OF NUCLEOPLASMIN, AN Nucleoplasmin (NP) is a pentameric, ring-shaped histone chaperone involved in chromatin remodeling processes such as sperm decondensation at fertilization. Monomers are formed by a core domain, responsible for oligomerization, that confers the protein a high stability and compactness and a flexible tail domain, that harbors a polyglutamic tract Stability Analysis for ODEsStability Analysis for ODEs Marc R. Roussel September 13, 2005 1 Linear stability analysis Equilibria are not always stable. Since stable and unstable equilibria play quite different roles in the dynamics of a system, it is useful to be able to classify equi-librium points based on their stability. Stability Analysis for Systems of Differential EquationsIn general the stability analysis depends greatly on the form of the function f(t;x) and may be intractable. In the case of an autonomous system where the function does not depend explicitly on t, x_ = f(x); t 0; x(0) = x 0 (2) the analysis is tractable. An equilibrium solution of this system is a constant vector c for which f(c) = 0.
In fact, this family of proteins has such diverse functions in cellular processes such as chromatin remodeling, ribosome biogenesis, genome stability, centrosome replication, cell cycle, transcriptional regulation, apoptosis, and tumor suppression. Of the members of this family, NPM1 is the most studied and is the main focus of this review. The role of nucleoplasmin in genome organisation and stabilityUsing Drosophila as a model, he showed that centromeres cluster together and associate with the nucleolus. This organisation depends on a network of factors associated with the protein NLP of the nucleoplasmin analysis of the stability and function of nucleoplasminphosmin family. A perturbation of this subnuclear architecture correlates with impaired genome stability. Thermodynamic Characterization of Nucleoplasmin Thermodynamic Characterization of Nucleoplasmin Unfolding:Interplay between Function and Stability Article in Biochemistry 47(30):7954-62 · July 2008 with 21 Reads How we measure 'reads' Transient stability analysis of power system using Transient stability analysis (TSA) of power system is gaining significant importance given the dwindling gap of power generation and demand as well as increasing penetration of intermittent renewable energy sources. Traditional approach to TSA has been primarily based on time-domain analysis or energy-function-based approach or based on common-Lyapunov function-based approach.
Jun 01, 2005 · This structural impairment suggests that hydrophobic interactions of Cys 45 are critical for the stability of the protein. Our studies allow to analyse for the first time the structural and functional properties of nucleoplasmin in its monomeric form.
