In biology, the chromosome scaffold is the backbone that supports the structure of the chromosomes. It is composed of a group of non-histone proteins that are essential in the structure and maintenance of eukaryotic chromosomes throughout the cell cycle. These scaffold proteins are responsible for the condensation of chromatin during mitosis. [1]
Chromosome scaffold has important role to hold the chromatin into compact chromosome. Chromosome scaffold is made of proteins including condensin, topoisomerase IIα and kinesin family member 4 (KIF4) [27] Chromosome scaffold constituent proteins are also called scaffold protein. In enzymatic reaction Large multifunctional enzymes that performs ...
the description of scaffold-attachment elements (SARs) by Laemmli and coworkers, which were thought to demarcate the borders of a given chromatin domain [2] the characterization of matrix-associated regions (MARs) the first examples of which supported the immunoglobulin kapp-chain enhancer according to its occupancy with transcription factors [ 3 ]
The chromosome scaffold, which is made of proteins such as condensin, TOP2A and KIF4, [34] plays an important role in holding the chromatin into compact chromosomes. Loops of thirty-nanometer structure further condense with scaffold into higher order structures. [35]
The structure of the condensed chromatin is thought to be loops of 30 nm fibre to a central scaffold of proteins. It is, however, not well-characterised. Chromosome scaffolds play an important role to hold the chromatin into compact chromosomes. Loops of 30 nm structure further condense with scaffold, into higher order structures. [21]
The non-histone proteins, are a large group of heterogeneous proteins that play a role in organization and compaction of the chromosome into higher order structures. They play vital roles in regulating processes like nucleosome remodeling, DNA replication, RNA synthesis and processing, nuclear transport, steroid hormone action and interphase ...
Scaffolding is a technique used in bioinformatics. It is defined as follows: [ 1 ] Link together a non-contiguous series of genomic sequences into a scaffold, consisting of sequences separated by gaps of known length.
Chromosome scaffold has important role to hold the chromatin into compact chromosome. Chromosome scaffold is made of proteins including condensin, topoisomerase IIα and kinesin family member 4 (KIF4) [7] Dinoflagellates are very divergent eukaryotes in terms of how they package their DNA. Their chromosomes are packed in a liquid-crystalline ...
