The major histone gene repeat (h22) of the sea urchin Psammechinus miliaris is transiently expressed for several hours during early embryonic development. Several major alterations in chromatin structure coincide with changes in the pattern of early histone gene expression and are reversed later. During the early (128-cell) blastula stages when h22 DNA is(More)
In a Hungarian family with severe decrease in triosephosphate isomerase (TPI) activity, 2 germ line-identical but phenotypically differing compound heterozygote brothers inherited 2 independent (Phe240Leu and Glu145stop codon) mutations. The kinetic, thermodynamic, and associative properties of the recombinant human wild-type and Phe240Leu mutant enzymes(More)
TPPP/p25 is a brain-specific protein, which induces tubulin polymerization and microtubule (MT) bundling and is enriched in Lewy bodies characteristic of Parkinson's disease [Tirián et al. (2003) Proc. Natl. Acad. Sci. U.S.A. 100, 13976-13981]. We identified two human gene sequences, CG1-38 and p25beta, which encoded homologous proteins, that we termed p20(More)
Sirtuins are a highly conserved class of NAD(+)-dependent lysine deacylases. The human isotype Sirt2 has been implicated in the pathogenesis of cancer, inflammation and neurodegeneration, which makes the modulation of Sirt2 activity a promising strategy for pharmaceutical intervention. A rational basis for the development of optimized Sirt2 inhibitors is(More)
The disordered Tubulin Polymerization Promoting Protein (TPPP/p25), a prototype of neomorphic moonlighting proteins, displays physiological and pathological functions by interacting with distinct partners. Here the role of the disordered N- and C-termini straddling a middle flexible segment in the distinct functions of TPPP/p25 was established, and the(More)
AbstrAct In a modern enterprise environment, many information resources are available to people working to produce valuable output. Due to technology proliferation , remote work access, and multiple geographical locations generating their own solutions for local infrastructure challenges, as well as the fact that modern professionals are tasked to make(More)
The hallmarks of Parkinson's disease and other synucleinopathies, Tubulin Polymerization Promoting Protein (TPPP/p25) and α-synuclein (SYN) have two key features: they are disordered and co-enriched/co-localized in brain inclusions. These Neomorphic Moonlighting Proteins display both physiological and pathological functions due to their interactions with(More)
Tubulin Polymerization Promoting Protein (TPPP/p25) is a brain-specific disordered protein that modulates the dynamics and stability of the microtubule network by its assembly promoting, cross-linking and acetylation enhancing activities. In normal brain it is expressed primarily in differentiated oligodendrocytes; however, at pathological conditions it is(More)
