Chromatin has a tendency to shift from a relatively decondensed (active) to condensed (inactive) state during cell differentiation due to interactions of specific architectural and/or regulatory proteins with DNA. A promotion of chromatin folding in terminally differentiated avian blood cells requires the presence of either histone H5 in erythrocytes or(More)
The intrinsically disordered proteins consist of partially structured regions linked to the unstructured stretches, which consequently form the transient and dynamic conformational ensembles. They undergo disorder to order transition upon binding their partners. Intrinsic disorder is attributed to histones H1, perceived as assemblers of chromatin structure(More)
Tremendous development of network systems and network applications observed over the last years has opened even more new research areas. The success of WWW applications, API exposition via web services or ubiquitous mobile access is immediately followed by significant challenges related to performance, security, or privacy issues of network systems. In(More)
The growing availability of network infrastructure is paralleled by the ever growing number of network applications. These applications rely on network services to answer business needs and enable the interaction of users and devices. Not surprisingly, the development of applications promotes further research in the field of network systems. In particular,(More)
This study was aimed at characterizing allelic variations of erythrocyte histone H1.b by comparing the electrophoretic patterns of histone H1.b from individuals of grey partridge (Perdix perdix) population. As two alloforms, H1.b1 and H1.b2, were discerned in the screening gels, the histone H1.b was regarded to be a polymorphic protein encoded by a gene(More)
Histone H1.0 belongs to the class of linker histones (H1), although it is substantially distinct from other histone H1 family members. The differences can be observed in the chromosomal location and organization of the histone H1.0 encoding gene, as well as in the length and composition of its amino acid chain. Whereas somatic (H1.1–H1.5) histone H1(More)
Two isoforms of the erythrocyte histone H1.a were identified in two conservative flocks of Rhode Island Red chickens and six conservative flocks of ducks. The H1.a1 and H1.a2 isoforms formed three phenotypes (a1, a2 and a1a2) and were electrophoretically similar in the two species. The frequency of phenotype and histone H1.a allele occurrence varied within(More)
Our goal was to characterize a phenotypic variation of the pheasant erythrocyte linker histone subtype H1.c. By using two-dimensional polyacrylamide gel electrophoresis three histone H1.c phenotypes were identified. The differently migrating allelic variants H1.c1 and H1.c2 formed either two homozygous phenotypes, c1 and c2, or a single heterozygous(More)
