The histone code hypothesis
WebThe 'histone code' idea is a hypothesis that suggests that modifications to the histone proteins that make up chromatin can function as a code or language to control gene expression. Histones are proteins that package DNA into compact structures called chromatin, with flexible 'tails' that protrude from the core particle of the nucleosome. ... WebThe most important concept in the histone code hypothesis is that the histone modifications serve to recruit other proteins by specific recognition of the modified histone, rather than …

WebMar 3, 2024 · Therefore, the “histone code” hypothesis has been proposed by Allis et al. in the early 21st century and supposes that the functions derived from rich histone language are extremely extensive and fine, involving all aspects of cell fate determination, such as replication of genetic code, cell adaptation to internal and external ... WebMar 28, 2011 · The histone modification code hypothesis suggests that nucleosomal code could control positioning in chromatin and the activation of effector proteins such as PARP1 (7, 8). Indeed, PARP1 protein interacts with histones, and the N-terminal domains of histones regulate activation of PARP1 enzymatic reaction ( 9 ).
WebThe histone code hypothesis proposes that combinations of histone modification could serve as specific signals that recruit protein domains to alter chromatin structure to either promote or suppress gene transcription (Turner, 2002). The histone code is a hypothesis that the transcription of genetic information encoded in DNA is in part regulated by chemical modifications (known as histone marks) to histone proteins, primarily on their unstructured ends. Together with similar modifications such as DNA methylation it is part of the … See more The hypothesis is that chromatin-DNA interactions are guided by combinations of histone modifications. While it is accepted that modifications (such as methylation, acetylation, ADP-ribosylation, ubiquitination, See more • Histone • Histone-modifying enzymes See more Unlike this simplified model, any real histone code has the potential to be massively complex; each of the four standard histones can be simultaneously modified at multiple different sites with multiple different modifications.

WebMar 28, 2005 · The “histone code” hypothesis was proposed as a generalization of the discovery that combinations of covalent histone modifications led to varied transcriptional outputs ( 1 – 4 ). One consequence of a combinatorial histone code is that DNA regulatory sequences provide only a partial explanation of gene regulation.
